摘要

Mesoporous poly (styrene-co-maleic anhydride)/silica hybrid materials have been prepared. The synthesis wasachieved by the HCl-catalyzed sol-gel reactions of tetraethyl orthosilicate (TEOS) and styrene-maleic anhydride copolymerin the presence of 3-aminopropyl triethoxysilane (APTES) as a coupling agent and citric acid as a nonsurfactant template orpore-forming agent

followed by ethanol extraction. Characterization results from nitrogen sorption isotherms and powder X-ray diffraction indicate the polymer-modified mesoporous materials with large specific surface areas(e.g. 900 m2/g) and pore volumes(e.g. 0.6cm3/g) could be prepared.As the citric acid concentration is increased

the specific surface areas

pore volumes and pore diameters of the hybrid materials increase.
