【摘要】：以兩親性導(dǎo)電聚合物聚(3,4-乙烯二氧噻吩)/聚苯乙磺酸(PEDOT/PSS)為表面活性劑、多壁碳納米管(MWCNTs)為導(dǎo)電填料,通過濃乳液模板法制備了聚苯乙烯導(dǎo)電泡沫復(fù)合材料(PS/MWCNTs)。采用掃描電子顯微鏡觀察了不同MWCNTs負(fù)載量對材料泡孔形貌的影響,并通過導(dǎo)電性能測試研究了材料的電導(dǎo)率隨MWCNTs及導(dǎo)電表面活性劑含量的變化規(guī)律。結(jié)果表明,填料負(fù)載量可以影響泡沫材料的泡孔形態(tài)與導(dǎo)電性能,并且具有表面活性劑性能的導(dǎo)電聚合物的引入大大提高了PS/MWCNTs泡沫材料的導(dǎo)電性。
[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.
