摘要:

用原位聚合方法在SIS(苯乙烯-异戊二烯-苯乙烯嵌段共聚物)橡胶基体中合成聚苯胺(PAn),可形成均匀复合的SIS-PAn导电橡胶膜.成膜后紧朝玻璃的膜面导电,而朝向空气的膜面却绝缘.膜中PAn的含量只有5.8%(质量分数)或An/SIS的投料比为0.2时,导电复合物膜的表面电阻和导电率即可分别达到300Ω/□和0.07S•cm-1. 分析了制备条件,包括PAn含量、酸量、氧化剂用量、表面活性剂用量、交联剂用量和模具材料等因素对SIS-PAn复合物导电性能的影响.

Abstract:

Conducting polyaniline (PAn) is synthesized in the SIS (Styrene-isoprene-styrene)matrix by the in--sift polymerization to form an uniformly mixed SIS--PAn conductive rubber membrane with the back (in contact with the glass) being conductive while the upside one being insulating thereof. The surface resistance and the conductivity of the conductive composite membrane are of 300Ω/□ and 0.07 S•cm-1, respectively, while the content of PAn in the membrane is only of 5.8% (or the feeding ratio of An/SIS is of 0.2). The effect of the preparation conditions including the content of PAn, acid, oxidant, surfactant and cross-linker, as well as the mold material on conductive properties of SIS/PAn membrane are analyzed.
