英文摘要	1991年Decher等将带相反电荷的聚电解质,于水溶液中交替沉积在片基上,制备了多层超薄膜[1],这种制膜方法现称为静电自组装.它操作简单,无需专用设备;一般在水体系进行,对环境友好;静电力比范德华力强,使它比LB膜稳定,所以近年来有很大发展[2].现在自组装成膜驱动力已从静电力扩展到氢键力、电荷转移相互作用、疏水相互作用等,用于组装的组分也从聚电解质扩展到多官能团小分子、胶体粒子、无机纳米颗粒,DNA、蛋白质等生物大分子等[3～11].; The self assembly between poly (4-diazonium styrene) (PDS) and poly(sodiumsulfonate styrene) ( PSS) was investigated. The mutilayer ultra thin films were fabricated layer-by-layer successfully. from PDS and PSS. After heating for 10 min at 70degreesC the multilayer film became very stable towards polar solvents. No considerable changes were observed for the heated film soaked in DMF (20degreesC) for 48 It, while the unheated film almost destroyed at same condition. The dramatic improvement in stability of the film towards' polar solvents should be attributed to the conversion of bonds between the layers of the film from ionic bond to covalent bond under heating.; 国家自然科学基金; http://gateway.webofknowledge.com/gateway/Gateway.cgi?GWVersion=2&SrcApp=PARTNER_APP&SrcAuth=LinksAMR&KeyUT=WOS:000183620800023&DestLinkType=FullRecord&DestApp=ALL_WOS&UsrCustomerID=8e1609b174ce4e31116a60747a720701 ; SCI(E); 中文核心期刊要目总览(PKU); 中国科技核心期刊(ISTIC); 中国科学引文数据库(CSCD); 1; 3; 442-444
