Ordered mesoporous polymers and polymer-silica anocomposites
A family of highly ordered mesoporous polymers and carbon frameworks, including p6m, Ia3d, Im3m Fm3m, and Fd3m mesostructures, has been prepared by the organic-organic assembly of triblock copolymers PEO-PPO-PEO, reverse copolymer PPO-PEO-PPO and PEO-PS with resols via solvent evaporation-induced self-assembly (EISA) strategy. By using pre-hydrolyzed TEOS as an inorganic co-precursor, highly ordered mesoporous polymer-silica and carbon-silica nanocomposites with interpenetrating networks were also synthesized via a triconstituent co-assembly. After the removal of silica component from carbon-silica nanocomposites, ordered mesoporous carbons then can be derived with large pore sizes of 6.7 nm, pore volumes of 2.0 cm3/g, and high surface area of 2470 m2/g.
