摘要/Abstract

摘要： 以苯胺、聚丙烯接枝磺化苯乙烯、氧化石墨烯为反应原料，以盐酸为掺杂剂，通过苯胺原位聚合及大分子反应制备了氧化石墨烯/聚丙烯接枝磺化苯乙烯/聚苯胺（GO/PP-g-SPS/PANI）层状结构的复合材料。研究了复合材料的体积电阻率及反应物配比对复合材料体积电阻的影响。分别采用FTIR、XPS对复合材料进行了结构分析，并采用SEM对复合材料结构形貌进行了表征，同时研究了将其添加到PP中的抗静电性能。研究结果表明： GO/PP-g-SPS/PANI制备最佳配比为质量比m_PP-g-SPS∶m_GO∶m_ANI=30∶15∶1时，材料体积电阻率最小为120Ω·mm。添加到PP中导电逾渗阈值为0.7%（质量分数），PP材料的体积电阻率达到最低值4.5×10¹⁰Ω·mm，比纯PP降低了6个数量级，拉伸强度提高了2.8MPa。SEM形貌图表明GO/PP-g-SPS/PANI以GO为骨架表面层状蜂窝结构，聚合物大分子镶嵌在GO片层间，与PP共混物界面具有良好的相容性。

Abstract: With polypropylene-grafted-sulfonated styrene, aniline and graphene oxide as raw materials with hydrochloric acid as the doping agent, the layered graphene oxide/polypropylene-grafted- sulfonated styrene/polyaniline(GO/PP-g-SPS/PANI) composites was prepared by in situ polymerization of aniline and macromolecular. The volume resistivity of the composites and the effect of the ratio of reactants on the volume resistivity of the composites were studied. FTIR and XPS were used to charactered the structure of the composites and SEM was used to analyze the morphology of the composites. The antistatic properties of the adding it to PP were also studied. The results showed that the optimal synthesis ratio for GO/PP-g-SPS/PANI were as follows:mass ratio m_PP-g-SPS:m_GO:m_ANI=30:15:1, and the minimum volume resistivity of the material was 120Ω·mm. The conductivity threshold was 0.7% by mass in PP, and the volume resistivity of the PP material reached a minimum value of 4.5×10¹⁰Ω·mm, which was 6 orders of magnitude lower than that of pure PP. The tensile strength of PP increased by 2.8MPa. SEM showed that GO/PP-g-SPS/PANI had GO as the surface layered honeycomb structure, and polymer macromolecules were embedded between GO slices. The PP blend interface had good compatibility.
