| 摘 要： | 采用原位聚合法,在SIS(苯乙烯-异戊二烯-苯乙烯嵌段共聚物)/LPB(液体聚丁二烯)橡胶基体中合成PAn(聚苯胺),形成单面导电的导电橡胶复合物.研究了基体聚合物交联度、苯胺、氧化剂用量和聚合反应时间等几种主要反应条件对复合物导电性的影响.导电层中PAn含量只有6.1%,导电面电导率就可达5.5S/m.该复合物的电导率:①随基体聚合物的交联度的增大而减小;②随苯胺用量的增大而增大;③随氧化剂用量的增大先增大后减小.

| Abstract: | PAn(polyaniline) was synthesized within the crosslinked SIS(styrene isoprene styrene)/LPB(liquid polybutadiene) rubber matrix by the in situ polymerization to form a mono face conductive rubber complex.The effects of the crosslinking degree of the polymer matrix,the amounts of aniline and the oxidant,as well as the polymerization time on the conducting properties of the complex were studied.The conductivity of the conductive surface is up to 5.5 S/m while the PAn content is only of 6.1%. The conductivity of the complex:(1)decreased with the increasing crosslinking degree of the matrix,(2)increased with the amount of aniline,(3)increased firstly and then decreased with the increasing amount of the oxidant. |
