Abstract

An all solid state electrochromic shutter was made incorporating a conductive polymer to modulate the microwave energy. The active polymer layer was polyaniline doped with camphorsulfonic acid which was switched between its conductive and insulting state using Li⁺ as the mobile ion and Li_xMn₂O₄ as the counter electrode. Changes in the transmission and reflection of X-band microwave energy were measured as a function of time and bias applied between the electrodes. With switching voltages up to ± 3 V modulation of nearly 10 dB was obtained in 10 minutes, but the cycle lifetime was limited.

Electromagnetic absorption/reflection manipulation by piezoelectric effect in PDMS/CZS/SWCNT/iron fabric hybrid composite
2024, Applied Materials Today
The development of externally controlled electromagnetic shielding materials for protecting high-end electronic devices operating in GHz frequencies in satellite, military, and other communication fields is a significant technological challenge. Previously developed foamed composites and capacitor-based shielding materials exhibit active modulation of reflection and absorption. However, the higher thickness of foamed composites and the costly complex manufacture process along with requirement of an external voltage source by capacitor-based shields constrain their direct usability in realistic electronic applications. Herein, a piezo-tuned polydimethylsiloxane (PDMS)/carbon-doped zinc stannate (CZS)/single wall carbon nanotube (SWCNT)/iron fabric-based hybrid composite is prepared which features piezo-voltage controlled shielding performance. In this composite, the electrostatic modification of iron fabric electrodes and PDMS/CZS, PDMS/SWCNT layers by piezo-voltage enables control of dynamic reflection/absorption ability of 14.5–20 GHz electromagnetic radiation (EMR). Additionally, this composite reveals a functional transition from EMR reflector to EMR absorber at higher than 14 mV piezo-voltage. At 14.5 GHz frequency, this piezo-composite (1.51 mm thick) attains an excellent total shielding (SE_T) performance of 87.8 dB along with >98 % EMR absorption capability at 30.6 kPa pressure tuned 243 mV piezo-voltage. Hence, this achievement not only reveals the strategies for developing shielding materials for the future of electronic applications but also boosts the advancement of self-adaptable electromagnetic shielding.
Multifunctional magneto-polymer matrix composites for electromagnetic interference suppression, sensors and actuators

Like metals, charge is carried in ICPs via free electrons, however, unlike metals, their conduction behavior can be controlled by redox doping/re-doping processes [121]. This attribute is attractive as it offers a possibility to tailor the conductivity of an ICP by altering the oxidation state as demonstrated in a solid state microwave switch [122]. In combination with a magnetic phase, this attribute offers promise toward tailorable EMI in FR-MPCs, permitting control over the proportion of EM reflection and absorption by the material.
Multi-functional fiber reinforced composites with magnetic properties offer great potential for enabling new applications in a diverse range of industry sectors, such as aerospace, automotive, biomedical, and civil infrastructures. By incorporating magnetic properties into existing fiber reinforced polymer composites (FRPC), it is possible to enhance their magnetic permeability and tailor their responses to external electrostatic, magnetostatic or electromagnetic fields. With improved magnetic permeability, these new multi-functional composites offer new solutions in waveform conditioning, structural health monitoring, integrated sensors, lightweight motors and actuators, and electromagnetic interference shielding. In these applications, the additional magnetic functionalities can be optimized to improve mass efficiency, environmental durability, affordable maintenance and safety. Herein we present a critical review of fiber-reinforced magneto-polymer matrix composites regarding material selection, microstructural design, functional mechanisms, manufacturing processes, recent innovative applications, challenges and future opportunities. Throughout, a specific focus is placed on the fundamental material properties and composite architectures required to achieve desired functions and meet overall multi-functional design objectives.
Electroactive (A<inf>3</inf>+B<inf>2</inf>)-type hyperbranched polyimides with highly stable and multistage electrochromic behaviors
2017, Electrochimica Acta
Multicolored electrochromic materials have attracted intense attentions due to their diverse smart applications. In this work, we demonstrate a facile strategy to realize multistage visible/near-infrared (vis/NIR) electrochromism by designing and synthesizing two kinds of novel hyperbranched polyimides (HBPIs) from a novel triamine as an A₃ monomer and two dianhydrides as B₂ monomers. The resulting HBPIs exhibit excellent solubility and thermostability. Cyclic voltammograms of the HBPIs films reveal four reversible redox couples along with five color conversions (colorless-yellow-red-indigo-black). Furthermore, the HBPIs exhibit superb electrochromic performances including continuous modulation over the entire visible region, short response time, high optical contrast, high coloration efficiency, excellent switching stability and long-term optical memory. Accordingly, these HBPIs are promising materials in the applications of electrochromism and even endowing difunctionality combining with supercapacitance.

Optically transparent and electrically conductive polymers have been attractive in the past two decades due to their benefits in various applications including solar cells, electrostatic dissipation, electromagnetic shielding, sensors, touch-sensitive screens, and alarm devices [1,2]. Furthermore, conducting polymers/magnetic nanocomposite have attracted great attention of the scientific community currently due to its high potential of technological industrial applications in various areas, such as electromagnetic interference shielding [3], rechargeable batteries [4], corrosion protection coatings [5], electrodes [6], gas separating membranes [7,8], microwave absorption [9], sensors [10–12], and microelectronic devices [13,14]. PANI as any conjugated polymer has some characteristics related to its molecular structure and bond alternation make the polymer infusible, insoluble in organic solvents and cannot be handled like thermoplastic polymers [15,16].
In this research, magnetite particles in a nanoscale were coated with three various weight percentages of poly (aniline co-o-anthranilic acid) copolymer. Aniline and o-anthranilic acid monomers were copolymerized in the presence of Fe₃O₄ nanoparticles via surface initiated polymerization method. Characterization of nanocomposites was carried out by several analysis techniques including; FT-IR, FE-SEM, TEM, XRD, TGA and UV–vis-Near infrared. FT-IR results showed that pended COOH groups of PANAA are physically interacted to magnetite nanoparticles. Magnetite nanoparticles enhanced the thermal strength of the nanocomposites in the range of 300–800 °C. The XRD analysis revealed that the average crystallite size ranges from 7.59 to 11.14 nm depending on PANAA weight percentage. Thin films of uniform spherical shape of PANAA/magnetite nanocomposite were fabricated by thermal evaporation technique. The values of E_g(direct) and E_g(indirect) decreased with increasing the thickness of PANAA, while the conductivity increased with increasing of PANAA thickness coated magnetite particles. The conductivity value ranged from 3.73 to 26.98 Ω⁻¹ cm⁻¹ at a photon energy 3.65 eV. Using the nanocomposites in photovoltaic applications was highlighted.
Structural, optical and dielectric properties of ZrO<inf>2</inf> reinforced polymeric nanocomposite films of polymethylmethacrylate (PMMA)
2016, Optik
A simplistic sol-casting technique was used to fabricate polymeric nanocomposite film of PMMA–ZrO₂. Phase analysis, micro-structure and chemical composition were examined through X-ray diffraction (XRD), Field emission scanning electron microscopy (FESEM) and Fourier transformed infra-red spectroscopy (FTIR). A significant enhancement in absorption coefficient of UV–vis absorption profile was observed with the increase in ZrO₂ content. Dielectric properties of the nanocomposite films were studied as a function of frequency and temperature in the ranges of 100 Hz–3 MHz and 313–373 K, respectively. The addition of ZrO₂ filler into PMMA markedly enhanced the dielectric constant (ε′ ∼ 26) and suppressed the loss (tan δ ∼ 0.06). Dielectric loss peaks were explained in terms of dielectric relaxation. The value of ac conductivity was found around 7.75×10⁻⁵ S m⁻¹ at 373 K and 3 MHz. The Conducting behavior of the nanocomposite film was ascribed to hopping mechanism. The synergistic combination of ZrO₂ and PMMA can be used as an appropriate candidate for high frequency capacitor application.

The conducting polymers are a new group of synthetic polymers which combines the chemical and mechanical properties of polymers with the electronic properties of metals and semiconductors [6]. Nowadays, conducting polymers have several applications in different areas such as microwave absorption, electronic displays, corrosion protection coating, electrochemical batteries, super capacitors, sensors, and electrodes [7–11]. They have extended p-conjugation with single- and double-bond alteration along its chain.
Polyaniline–NiFe₂O₄ nanocomposites (PANI–NiFe₂O₄) with different contents of NiFe₂O₄ (2.5, 5 and 50 wt%) were prepared via in situ chemical oxidation polymerization, while the nanoparticles nickel ferrite were synthesized by sol–gel method. The prepared samples were characterized using some techniques such as Fourier transforms infrared (FTIR), X-ray diffraction (XRD), scanning electron microscopy (SEM) and thermogravimetric analysis (TGA). Moreover, the electrical conductivity and optical properties of the nanocomposites were investigated. Pure (PANI) and the composites containing 2.5 and 5 wt% NiFe₂O₄ showed amorphous structures, while the one with 50 wt% NiFe₂O₄ showed a spinel crystalline structure. The SEM images of the composites showed different aggregations for the different nickel ferrite contents. FTIR spectra revealed to the formation of some interactions between the PANI macromolecule and the NiFe₂O₄ nanoparticles, while the thermal analyses indicated an increase in the composites stability for samples with higher NiFe₂O₄ nanoparticles contents. The electrical conductivity of PANI–NiFe₂O₄ nanocomposite was found to increase with the rise in NiFe₂O₄ nanoparticle content, probably due to the polaron/bipolaron formation. The optical absorption experiments illustrate direct transition with an energy band gap of E_g = 1.0 for PANI–NiFe₂O₄ nanocomposite.
