摘　　要：以丁苯吡胶乳（ＰＳＢＲＬ）为稳定剂，苯胺（Ａｎ）进行氧化聚合，制得的导电ＰＡｎ／ＰＳＢＲＬ复合聚合物可直接浇铸成膜，亦可经破乳后用其沉淀物经热压成膜。氧化聚合条件：［ＨＣｌ］＝１．４ｍｏｌ／Ｌ，［Ａｎ］＝０．５ｍｏｌ／Ｌ，［氧化剂］＝０．２５ｍｏｌ／Ｌ。胶膜性质：当该复合聚合物中ＰＡｎ含量约为５０％时，电导率可达５×１０２Ｓ／ｍ左右，拉伸强度约１３ＭＰａ，扯断伸长率为５３％，在空气气氛中贮存２８ｄ电导率基本不变。Aqueous polyaniline (PAn)latex was prepared by chemical oxidative polymerization using poly (butadiene-styrene-2-vinyl pyridine) copolymer latex as a stabilizer.The processing ability of PAn was improved.Thin composite film of less than 0.2 mm was prepared by casting PAn latex on glass,or the thick composite film of more than 0.2 mm was obtained by pressing.The composite film had high conductivity,good mechanical properties and stability in air.The influence of copolymer latex as a stabilizer on the synthesis of PAn latex and the conduction mechanism of the film were investigated.The micrograph of composite latex particles and composite film section were observed by TEM and SEM.
