Formation of nanoporous and nanocrystalline anatase films by pyrolysis of PEO–TiO2 hybrid films

Photocatalytic membranes prepared by embedding porous Zr-doped SiO2shell/TiO2core particles with expanded channels into polyvinylidene fluoride for cleaning wastewater

“…[2][3][4][5] Furthermore, immobilization of TiO 2 nanoparticles on polymeric supporters has drawn increasing attention for recovery and separation of TiO 2 powder aer photocatalytic process because of the small size of TiO 2 . [6][7][8][9] However, the polymeric supporters can still be photodegraded by TiO 2 nanoparticles. 10,11 Therefore, in order to avoid the photodegradation of polymeric supporters based on ensuring the photocatalytic activity of TiO 2 , TiO 2 modication such as the SiO 2 shell/TiO 2 core structure and TiO 2 capsulated in nanovoid microcapsule of poly(vinylidene uoride) supporter etc.…”

In situ compatibilization between polystyrene‐grafted nano‐sized TiO2 and polypropylene with Friedel‐Crafts catalyst

“…As a strong UV absorber, nano‐sized TiO 2 can improve the resistance to UV aging of polymers without shortcomings such as toxicity, short‐life, etc. compared with organic UV absorbers 9, 10. However, the raw TiO 2 nanoparticles aggregate easily when dispersed in polymer matrix, such as PP, by melt blending process because of higher viscosity of matrix and poor compatibility between TiO 2 nanoparticles and polymer matrix 11.…”
