将阳离子苯丙、水性环氧树脂、脲醛树脂两两复配成复合乳液,并与聚苯胺乳液进行混合,制得涂液,研究了复合乳液中成膜物的种类、浓度以及复合乳液与聚苯胺乳液的配比,对涂膜表观和电导率的影响。结果表明,采用阳离子苯丙与水性环氧树脂的复合乳液,并与聚苯胺乳液按质量比4 颐3 混合,得到的涂膜表观好,最高电导率可达0. 004 51 S/ cm。

The cationic styrene-acrylic emulsion, waterborne epoxy emulsion and urea resin were compounded with each other and then the composite emulsion were mixed with polyaniline emulsion. The type and concentration of film former and the ratio of composite emulsion to polyaniline emulsion and their influences on the film-forming property and electrical conductivity were investigated. The results show that excellent film can be obtained when mass ratio of cationic styrene-acrylic and water-borne epoxy composite emulsion to polyaniline emulsion is 4 颐3 and maximum electrical conductivity can reach 0. 004 51 S/ cm
