中文摘要：
以纳米乙炔炭黑在反应体系中的聚集体为模板,采用化学氧化法制备了多孔形貌的聚苯胺。讨论了乙炔炭黑经硝酸液相氧化处理对聚苯胺/炭黑复合材料形貌、导电性及热性能的影响。研究结果表明,在聚苯胺掺杂酸盐酸用量增加到80mL时两种复合材料都具有多孔结构,并且由于炭黑经硝酸液相氧化后分散性及表面性质得到改善,产物呈现出明显的一维线性结构,该复合材料电导率高达5.55S/cm。多孔复合材料热分解温度均在430℃左右。
英文摘要：
Polyaniline / carbon black porous composites were prepared by using the conductive carbon black as a template and by in situ chemical oxidization polymerization.The impact of CB oxidation on morphology,thermal properties and conductivity of the composites was studied.The results showed that the composites,prepared with HCl solution which of the volume is 80mL,are porous.Because the grain-size characters of distribution and surface are improved after CB oxidation,the morphology of the polyaniline / oxidated carbon black composite is fibre texture and the conductivity value is as high as 5.55S/cm.The decomposed temperatures of the porous composites are about 430℃.
