模板浸出法制备多孔聚苯乙烯膜的研究
Fabrication of porous polystyrene films by using template-leaching process
摘要
Abstract
Porous polystyrene membranes are successfully prepared on solid substrates by a template-leaching technique. The toluene and starch are. employed as solvent and leaehable component, respectively. Siareh is mixed with polystyrene with the starch/polystyrene weight ratio of 1:1,1:2,1:3, separately. Each mixture is dissolved in toluene in order to produce a blend of 1%, 3%, 5% by weight of polystyrene. Each blend is coated by spin-coating method to produce a thin polystyrene/starch film. By acidic leaching of the starch particles from the films, the porous films with ordered and homogeneous structures are formed via controlling the degree of soluhility. Subsequently, the films are characterized by contact angle measurement, scanning electron microscopy (SEM) and Fourier infrared spectroseopic analysis (FTIR). The results indicate that the porous structure of the films is affected by many experimental factors, and the type and concentration of inorganic acids are of the most important. By comparison of three different inorganic- acids such as HCI, H2SO4, or HNO3, starch particles are best removed in dilute HNO3 solution. The obtained pores are micro-meter size with a narrow distribution.关键词
