摘要： 用原位乳液聚合法在环氧丙烯酸树脂(EA)中合成出了十二烷基苯磺酸掺杂的聚苯胺(PNAI-DBSA)与EA的混合物,脱水干燥后加入交联单体、引发剂2,4,6-二苯基氧化膦(TPO)等,混合均匀后用紫外光固化形成PNAI-DBSA/EA互穿网络导电膜。通过力学性能测定,研究了PANI-DBSA粒子含量、交联单体种类及用量等对导电膜力学性能的影响。结果表明:PANI-DBSA的含量和交联单体的种类及用量对导电膜的力学性能有明显影响,在PANI-DBSA、TPO、交联单体分别为体系总质量的15%、4%和50%时,固化40 s,乙氧基化三羟甲基丙烷三丙烯酸酯(EO-TMPTA)导电膜的拉伸强度最大,达15.24 MPa;丙烯酸羟乙酯(HEA)导电膜的断裂伸长率最大,达到24.8%。利用透射电镜和红外光谱分析分别对PANI-DBSA和导电膜进行了分析和表征。

Abstract: The nano-polyaniline/epoxy acrylate(pnai-dbsa/EA )mixture was synthesized by insitu emulsion polymerization. Then it was added with diluted cross-linking monomer and initiating agent stirring to well-distributed. At last, the PNAI -DBSA/EA interpenetrating networks conductive film was prepared through UV curing. The influence of cross-linking monomer and PANI-DBSA to the conductive films mechanical property was researched by tests. The results show that when the content of PANI-DBSA is 15%, the initiating agent dosage of TPO is 4%, the content of cross-linking monomer EO-TMPTA is 50% and the curing time is 40 s, the single degree functionality of hydroxyl ethyl methacrylate UV curing films breaking elongation reaches the maximum. which is 24.8%. Besides. the PANI-DBSA and the conductive film were tested and analysed by TEM and FT-IR.
