【摘要】 乳液聚合法聚合乳酸掺杂聚苯胺。再使用开炼机混炼PP/聚苯胺,最后平板硫化仪得到永久抗静电聚苯胺/PP。研究发现,聚苯胺/PP复合材料的相容性好。通过掺杂,乳酸中解离出的H+与聚苯胺分子链上的N原子结合,使聚苯胺获得永久、稳定的导电性。结果证明,随着聚苯胺的添加量,体积电阻减小三个数量级,冲击强度、拉伸强度和硬度足以满足很多应用的要求。更多还原

【Abstract】 Polyaniline doped with lactic acid was synthesized by emulsion polymerization. The antistatic polyaniline /PP composites were prepared after polyaniline was fully mixed in PP by the open smelting machine and the flat vulcanizing machine. The results indicated that the compatibility of polyaniline /PP composites was good. By doping,the H+which dissociated from lactic acid combined with the N atom of polyaniline molecular chains,so that the conductivity of polyaniline was lasting and stable. With the increase of polyaniline,volume resistance decreased three orders of magnitude,the impact strength,tensile strength and hardness was enough to meet the requirements of many applications.更多还原
