【摘要】：以两亲性导电聚合物聚(3,4-乙烯二氧噻吩)/聚苯乙磺酸(PEDOT/PSS)为表面活性剂、多壁碳纳米管(MWCNTs)为导电填料,通过浓乳液模板法制备了聚苯乙烯导电泡沫复合材料(PS/MWCNTs)。采用扫描电子显微镜观察了不同MWCNTs负载量对材料泡孔形貌的影响,并通过导电性能测试研究了材料的电导率随MWCNTs及导电表面活性剂含量的变化规律。结果表明,填料负载量可以影响泡沫材料的泡孔形态与导电性能,并且具有表面活性剂性能的导电聚合物的引入大大提高了PS/MWCNTs泡沫材料的导电性。
[Abstract]:The amphiphilic conductive polymer poly (3o 4-ethylenedioxythiophene) / polyphenylene ethanesulfonic acid (PEDOT/PSS) was used as surfactant and multi-walled carbon nanotube (MWCNTs) as conductive filler. Polystyrene conductive foam composites (PS/MWCNTs) were prepared by concentrated emulsion template method. The effect of different MWCNTs loading on the morphology of porous materials was observed by scanning electron microscope (SEM). The change of conductivity with MWCNTs and the content of conductive surfactants was studied by electrical conductivity test. The results show that the amount of filler loading can affect the foam morphology and conductivity, and the introduction of conductive polymers with surfactant properties greatly improves the conductivity of PS/MWCNTs foam materials.
