Higher UV-shielding ability and lower photocatalytic activity of TiO2@SiO2/APTES and its excellent performance in enhancing the photostability of poly(p-phenylene sulfide)

U–TiO₂ is successfully coated with SiO₂ and subsequently well modified by APTES, and a core–shell structure exists on TiO₂@SiO₂ and TiO₂@SiO₂/APTES, which greatly reduces aggregation of the TiO₂ nanoparticles.
