聚(3,4-乙撑二氧噻吩)复合材料的制备及性能研究

Preparation and Properties of Poly(3,4-ethylenedioxythiophene)

以带亲水基的四种不同的磺酸为掺杂剂,通过化学氧化聚合制备了相应的聚(3,4-乙撑二氧噻吩)(PEDOT)复合材料,通过红外色谱和SEM进行表征,对比测试了掺杂剂种类用量、氧化剂的配比以及反应时间等影响因素对产品电导性的影响。结果表明,以樟脑磺酸作掺杂剂的PEDOT的复合材料空间结构特殊,导电性最好。

With hydrophilic group of four different sulfonic acid as the doping agent,through chemical oxidative polymerization of preparation of the corresponding poly(3,4-ethylenedioxythiophene)(PEDOT)composite material,through infrared chromatography and were characterized by SEM,the contrast test of the variety of doping agent dosage,ratio of oxidant and reaction time on influence factors on the conductivity of products.The results show that the composite material space structure of PEDOT with camphor sulfonic acid as dopant is special and the conductivity is the best.
