摘要
以聚氯乙烯（ＰＶＣ）为基体材料，吸附一定量的苯胺单体（ＡＮＩ）后，通过氧化剂使ＡＮＩ在ＰＶＣ中发生就位（ｉｎｓｉｔｕ）化学氧化聚合反应，制备了电导率高达０．２３３Ｓ／ｃｍ的聚苯胺－聚氯乙烯（ＰＡＮＩ－ＰＶＣ）原位复合材料。研究了单体用量、氧化剂种类及反应工艺条件对复合材料性能的影响，确定了合适的制备条件。ＳＥＭ观察的结果表明ＰＡＮＩ在ＰＶＣ中分散非常均匀，在ＰＡＮＩ含量较少时即能形成导电通路。
In situ polyaniline polyvinylchloride (PANI PVC) composites with high conductivity (0.233 S/cm) were prepared by in situ chemically oxidative polymerization of aniline sorbed by PVC. The effects of monomer content, oxidant species and polymerization condition on the properties of composites were investigated. The suitable preparation condition has been determined. The SEM results indicated that PANI is dispersed very well in PVC and an excellent conducting network is formed even if the PANI content is low.
