Chemically Modify On The Surface Of Macroporous Polystyrene Materials

Porous materials have been widely used as catalytic surfaces and supports, separation and adsorbent media, biomaterials, chromatographic materials, and thermal, acoustic, and electrical insulators because they features high ratio of surface to volume, adsorbent capacity and special properties. Surface-macroporous polystyrene with sub-micrometer pores and a surface thickness of 10 μm has been synthesized using a maleic anhydride-alt-vinyl acetate copolymer as a template, followed by removal of the template with water, ethanol or acetone.The purpose of this essay is to make use of template to synthesize polystyrene with porous on the surface. Mean while, active groups were introduced to surface and it talked about active groups' reaction later. Discussed the effect of the two technich two ways method and one way method to introduce the active groups (acid anhydride) to the multi-holes surface of polystyrene separately. We studied the effect of...
