一种导电聚苯胺-碳纳米管复合物的合成方法
摘要：
本发明涉及一种导电聚苯胺?碳纳米管复合物的合成方法，其特征在于，制备步骤和条件如下：(1)碳纳米管水溶液的制备：将碳纳米管粉末与蒸馏水混合，配制成质量浓度为5?10％的碳纳米管水溶液；(2)原位聚合得到聚苯胺?碳纳米管复合物：将苯胺的硫酸溶液和碳纳米管浆料混合，超声分散，逐滴加入硫酸铵继续超声，转到磁力搅拌器搅拌，室温反应，得到灰黑色沉淀物，反应完毕用去离子水和甲醇分别离心清洗反应物，得到聚苯胺?碳纳米管复合物。本发明可以解决聚苯胺结构松散、导电性不足的缺点，是一种理想的电极材料产物；并且利用超生分散，充分混合，从而加快反应进程，缩短反应时间，得到更为均匀的复合物。
摘要（英）：

The invention relates to a synthesis method of a conductive polyaniline and carbon nanotube compound.The method is characterized by including the steps of firstly, preparing a carbon nanotube water solution, wherein carbon nanotube powder is mixed with distilled water to prepare a carbon nanotube water solution with mass concentration of 5-10%; secondly, conducting in-situ polymerization to obtain the polyaniline and carbon nanotube compound, wherein a sulfuric acid solution of aniline and carbon nanotube paste are mixed and dispersed by ultrasonic waves, ammonium sulfate is dropwise added to continue ultrasonic treatment, the materials are transferred into a magnetic stirrer to be stirred, reaction is conducted at the room temperature to obtain an ash black deposit, and reactant is centrifuged and cleaned through deionized water and methyl alcohol after reaction ends to obtain the polyaniline and carbon nanotube compound.The compound can overcome the defects that polyaniline is loose in structure and not sufficient in conductivity and is an ideal electrode material product; due to ultrasonic dispersing and sufficient mixing, reaction progress is accelerated, reaction time is shortened, and the more uniform compound is obtained.
