| Abstract: | Poly(dimethylsiloxane)-poly(ethylene oxide)(PDMS-PEO) diblock copolymer has been used as template in methylphenylsiloxane(MPS) resin matrix to fabricate porous MPS/PDMS composite.The structure of resulting materials has been characterized by transmission electron microscopy(TEM),nitrogen-sorption measurements and 1H-nuclear magnetic resonance(1H NMR).Results show that MPS/PDMS composites with pore structures and large pore sizes have been obtained.Through calculation,the BET surface area,pore volume and mean pore size of porous MPS/PDMS composites are 285 m2/g,0.21 cm3/g,and 24.2 nm,respectively. |
