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120 ℃时,分别表现为略有增重和失重;高于120 ℃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,与掺杂氧的来源有关。
Polypyrrole was chemically synthesized. TG-DTA and IR measurement were performed to study the effect of temperature on polypyrrole. The samples was detected under N2 or air, respectively. Some weight gain and loss were observed at temperature less than 120 ℃ for the samples prepared in N2 and air respectively. The different TG curves of the same samples in N2 and air at elevated temperature were correlations with the different sources of a dopant O2.
