Organic–Inorganic Hybrid Mesoporous Polymers Fabricated by Using (CTA)2S2O8 as Self-Decomposed Soft Templates

Organic–inorganic hybrid mesoporous polymers were successfully synthesized by using a template-directed free radical polymerization technique in aqueous solution at 0–5 °C with oxidative complexes as self-decomposed soft templates. The oxidative complexes ((CTA)2S2O8), which were formed between anionic oxidant (S2O82–) and cationic surfactant (cetyltrimethylammonium bromide, CTAB) at 0–5 °C, can be automatically decomposed due to the reduction of S2O82–. No additional treatment was needed to remove the templates. The reactive functional monomer, 3-(trimethoxysilyl)propyl methacrylate (TMSPMA), was used as main monomer. Styrene was used as the comonomer. With simultaneous free radical copolymerization of TMSPMA and styrene, condensation of methoxysilyl groups, and the self-decomposition of (CTA)2S2O8, organic–inorganic hybrid mesoporous polymers were successfully obtained. The mesoporous structures and morphologies of the resultant hybrid mesoporous polymers were found to be strongly dependent on the feed ...
