摘　　要：为研究本征态聚苯胺对非织造过滤材料的驻极性能和过滤性能的影响,制备具有良好性能的非织造复合材料。采用原位聚合法制备了本征态聚苯胺/聚丙烯(PANI/PP)复合材料,通过SEM扫描电镜对复合材料的表面形态进行了表征,测试分析及比较本征态聚苯胺/聚丙烯(PANI/PP)复合材料和PP材料电晕驻极后的表面静电势和电荷储存性能及过滤性能。实验结果表明,本征态聚苯胺/聚丙烯(PANI/PP)复合材料具有较好的驻极性能,本征态聚苯胺(PANI)能够大幅提升聚丙烯(PP)材料的表面静电势,同时在最佳驻极条件下本征态聚苯胺/聚丙烯(PANI/PP)复合材料比聚丙烯(PP)材料的电荷储存性能更加稳定,电荷保留率为60%左右,且过滤效率高出20%左右。In order to study the effect of eigenstate-polyaniline on the charging and filtration properties of nonwoven filter materials,non-woven composite material with good properties was prepared.The eigenstate-polyaniline/polypropylene(PANI/PP)composites were prepared by in-situ polymerization.The surface morphology of the composites was characterized by SEM,and the surface electrostatic potential,charge storage properties and filtration properties of the eigenstate-polyaniline/polypropylene(PANI/PP)composites and PP after corona charging were tested and compared.The experimental results show that the eigenstate-polyaniline/polypropylene(PANI/PP)composite had good electret performance,and the eigenstate-polyaniline(PANI)could greatly improve the surface electrostatic potential of polypropylene(PP).Under the optimal charging conditions,the eigenstate-polyaniline/polypropylene(PANI/PP)composites had more stable charge storage performance than polypropylene(PP).The charge retention rate was about 60%and its filtration efficiency was higher up to 20%.
