摘　　要：为改善聚苯胺（ＰＡｎ）表面的亲水性，在化学氧化法制备的聚苯胺片表面接枝共聚丙烯酰胺（ＡＡｍ）．研究了Ａｒ＋辉光放电等离子体处理ＰＡｎ表面以及共聚条件对表面接枝共聚反应的影响．结果表明丙烯酰胺可以在酸掺杂表面进行接枝共聚反应；Ａｒ＋辉光放电等离子体处理ＰＡｎ表面后可以提高ＡＡｍ在ＰＡｎ表面上的接枝量。通过反射ＦＴＩＲ，ＳＥＭ，ＸＰＳ等研究表征了接技改性后ＰＡｎ表面结构和形态。测定了相应的ＰＡｎ表面与水的接触角以及电导率。The graft copolymerization of acrylamide(AAm)on the surface of acd-doped polyani-line(PAn)is studied. The effects of surface treatment of PAn and various copolymerizationconditions have been investigated.It has been found that the surfaces of acid-doped PAnhave been modified to higher hydrophilicity after grafting with AAm and if Ar+ glow dis-charge plasma(Ar+ plasma)treatment is performed before graft copolymerization,the graft-ing density of AAm on the surface of acid-doped PAn is increased. The surface compositionand morphology of PAn modified by grafting AAm have been characterized by reflectionFTIR,SEM and XPS.
