Abstract

This work reviews our recent achievements on a novel generation of UV/sunlight responsive silica nanoparticles (SiO2 NPs) and smart textiles. Photoresponsive organic – 2H-naphtho[1,2-b]-pyran (2H-NPT) and 3H-naphtho[2,1-b]pyran (3H-NPT) derivatives – and inorganic – phosphomolybdic acid (PMo12) – compounds were selected to tune the photochromic response and color palette range of the SiO2 NPs and corresponding smart textiles. The SiO2 NPs were functionalized by covalent post-grafting of 2H-NPTs and 3H-NPTs, and by non-covalent electrostatic immobilization of PMo12. The resulting hybrids were incorporated onto fabric substrates by screen-printing and within fibers through advanced fiber-spinning processes − wet spinning and melt spinning − at pre-industrial scale.
