摘　　要：化学氧化法制备的聚苯胺表面的亲水性差。本文在本征态和不同酸掺杂态聚苯胺的表面上接枝共聚丙烯酸和丙烯酰胺，明显地改善了聚苯胺的表面亲水性。结果显示，聚苯胺表面经过等离子体处理后，有利于丙烯酸和丙烯酰胺在聚苯胺表面上的接枝共聚，随着接枝量增多，导电率则随之有所下降。此外，利用ＳＥＭ和反射ＩＲ表征了改性后聚苯胺表面的形态和结构。In this paper,the intrinsic and different types of acid-doped polyaniline (PAn),synthesised with chemical method, have been subjected to plasma treatment and graft copolymerization with acrylamide (AM) or acrylic acid (AA). The effects of different surface treatment have been studied by measuring the water contact angle and conductivity. The reaults showed that the surface of PAn was modified to hydrophilic by grafting AM or AA after plasma treatment. The surface compsition and morphology of PAn after different surface treatment were characterized by internal reflection FT-IRand SEM.
