Description

TiO2 nanoparticles supported on aluminosilicate particles modified with cationic surfactant by simply mixing them in water could protect resin from photocatalytic decomposition while decomposing acetaldehyde via photocatalic reaction. When anionic polymer dispersants with different structures and molecular weights were adsorbed on TiO2 nanoparticles for the improvement of decomposition efficiency, the TiO2 nanoparticles supported on aluminosilicate particles modified with cationic surfactant exhibited protection effect of resin, depending on the structure and molecular weight of anionic polymer dispersant. This trend was not observed for the TiO2 nanoparticles dispersed by anionic polymer dispersant. The interaction between TiO2 nanoparticles and aluminosilicate surface was analyzed with the colloid probe AFM method. The protection effect of resin appears when a decrease in the adhesive force and weak repulsive force were observed.
