摘　　要：用化学氧化聚合法合成聚吡咯 (PPY) ,利用热重 (TG) -差热分析 (DTA)和红外光谱 (IR)对其升高温度发生的变化进行了研究。氮气和空气中合成的样品在空气中加热低于 12 0℃时 ,分别表现为略有增重和失重 ;高于 12 0℃时 ,失重特点相同。同一样品 ,在氮气和空气中加热表现出较大的差异 。Polypyrrole was chemically synthesized. TG DTA and IR measurement were performed to study the effect of temperature on polypyrrole. The samples was detected under N 2 or air, respectively. Some weight gain and loss were observed at temperature less than 120 ℃ for the samples prepared in N 2 and air respectively. The different TG curves of the same samples in N 2 and air at elevated temperature were correlations with the different sources of a dopant O 2.
