Higher UV-shielding ability and lower photocatalytic activity of TiO 2 @SiO 2 /APTES and its excellent performance in enhancing the photostability of poly(p-phenylene sulfide)

U–TiO 2 is successfully coated with SiO 2 and subsequently well modified by APTES, and a core–shell structure exists on TiO 2 @SiO 2 and TiO 2 @SiO 2 /APTES, which greatly reduces aggregation of the TiO 2 nanoparticles.
