Abstract

The aim of this research was to synthesize surface-treated nano-titanium dioxide (TiO2) particles and incorporate them into water-based acrylic systems, which could offer long-term protection for UV-sensible wood substrates. To suppress the photocatalytic activity, the surface of TiO2 nanoparticles in rutile crystal structure was coated with amorphous silica (SiO2) layer. The amounts of SiO2 were 5 and 10 wt%, respectively. Formation of SiO2 layer on TiO2 surface was analyzed using scanning and transmission electron microscopy. SiO2 layer thickness increases as a function of precursor loading. In addition, the influence of SiO2 loading on rutile UV-protective properties was determined. Transparent UV-protective coatings were developed by incorporating surface-treated nano-TiO2 into water-based acrylic stain. The particle size distribution was determined using dynamic light-scattering measurements, which indicate that the suspension of surface-treated rutile is stable against agglomeration. Furthermore, the color change and ability of protection against UV light of coatings after nanoparticles incorporation were determined. TiO2, surface treated with 10 wt% of SiO2, yielded coatings of higher transparency; however, TiO2, surface treated with 5 wt% of SiO2, improved UV protection.
