将化学氧化法制备的酸掺杂聚苯胺（ＰＡｎ）压制成片，直接或经过氩气辉光放电等离子体处理后，在水溶液中以过硫酸氨为引发剂接枝共聚丙烯酸（ＡＡ）。考察了有关实验条件和诸因素对表面接枝共聚的影响。并通过反射ＩＲ、ＳＥＭ和ＸＰＳ分析了接枝表面的结构和形态。结果表明，在过硫酸氨的引发作用下，ＡＡ能在酸掺杂的ＰＡｎ表面发生接枝共聚反应，而经过氩气辉光放电处理后的ＰＡｎ表面，则更有利于提高丙烯酸的接枝密度。在ＰＡｎ表面ＡＡ的接枝量愈多，其表面亲水性愈好，而导电率则随之下降。ＳＥＭ照片显示ＰＡｎ表面接枝的ＡＡ呈絮状分布。
Acid-doped polyaniline (PAn) prepared by the chemical oxidation method is pressed into a sheet, directly or after argon glow discharge plasma treatment, and then grafted with acrylic acid (AA) by using ammonium persulfate as an initiator in an aqueous solution. The effects of experimental conditions and various factors on the surface graft copolymerization were investigated. The structure and morphology of the graft surface were analyzed by reflection IR, SEM and XPS. The results showed that AA could graft copolymerization on acid-doped PAn surface under the action of ammonium persulfate, while PAn surface after argon glow discharge treatment was more beneficial to improve the graft density of acrylic acid . The more grafted AA on the surface of PAn, the better the surface hydrophilicity and the lower the conductivity. The SEM images showed that the grafted AA on the PAn surface was flocculent.
