二种无机酸掺杂聚苯胺的制备及其导电性能影响因素研究

Study on the Conductive Performance Factors the Preparation of Two Inorganic Acid Doped Polyaniline

通过四探针测试仪对二种无机酸掺杂聚苯胺的导电率进行了测试,用控制变量的方法研究了掺杂酸的种类和浓度、引发剂的量、合成温度等对聚苯胺导电率的影响。研究发现,引发剂与苯胺单体的摩尔量相同、盐酸浓度为2mol/L、温度为0℃时合成的聚苯胺的导电率最佳。

The conductivity of the two kinds of inorganic acid doped polyaniline was tested by four point probe tester, and studied type and concentration, the amount of initiator, the synthesis temperature on the influence of polyaniline conductivity by using control variable method. It is found that the conductivity of polyaniline is the best when the molar mass of initiator and aniline monomer is the same, the concentration of hydrochloric acid is 2mol/L, and the temperature is 0°C.
