摘要(Abstract)：
采用界面聚合法合成了聚联苯胺,聚(3,3-二甲氧基联苯胺)和聚(3,3-二甲基联苯胺).利用红外光谱(FT-IR),紫外可见吸收光谱(UV-v is),电子扫描显微镜(SEM),X-射线衍射(XRD),循环伏安(cyclic vo ltam-ogram)等测试方法,对聚合物进行了表征.从环取代基的电子效应和立体效应以及界面聚合反应的特点,初步探讨了环取代基对界面聚合法合成的聚合物分子链的结构,结晶性,颗粒形貌以及电化学活性的影响.结果表明,界面聚合法合成聚联苯胺表现出尺寸在微米范围内的棒状分布,在紫外可见吸收光谱中,相对于聚联苯胺,聚(3,3-二甲氧基联苯胺)的吸收峰发生红移.聚(3,3-二甲氧基联苯胺)的结晶性在三种聚合物中相对较好.聚(3,3-二甲氧基联苯胺)的氧化还原峰电位与其余两种聚合物相比,有负移.说明界面聚合得到的聚合物的分子链的结构,结晶性,颗粒形貌以及电化学活性由环上取代基的电子效应和立体效应不同而有所变化.
