Abstract

The article introduces a novel method for homogeneous and stable dispersion of carbon nanotubes (CNTs) using cellulose in NaOH/thiourea aqueous solution. This approach overcomes the challenges of severe agglomeration and requires only mild mechanical stirring, making it a cost-effective and scalable solution. The method relies on the formation of a core-sheath structured CNT-cellulose-NaOH-thiourea inclusion complex, which enhances the dispersity and stability of CNTs. The versatility of the cellulose/CNT dispersion is demonstrated by its application in various CNT-based materials, including microspheres, fibers, films, and monoliths. Additionally, the dispersion can be used as an ink for printing and dyeing, highlighting its potential for flexible and wearable device fabrication. The study combines experimental and theoretical analyses, providing a comprehensive understanding of the dispersion mechanism and the potential of cellulose-stabilized CNT solutions in practical applications.
