Electrical conductivity properties of P(MMA-St)/MWNTs composites

  • 摘要: 采用原位乳液聚合法制备了甲基丙烯酸甲酯-苯乙烯共聚物(P(MMA-St))包覆多壁碳纳米管(MWNTs)复合材料.研究了MWNTs含量和共聚物单体配比对复合材料导电性能的影响;用 SEM、FTIR、Raman和XPS等手段,探究了复合材料结构、相互作用与性能之间的关系.结果表明,MWNTs的加入提高了复合材料的热稳定性和电导率:当MWNTs含量一定,提高PMMA链段含量时,共聚物与MWNTs的作用增强,共聚物更易均匀地包覆在MWNTs表面,呈现出优异的热、电性能.
