Synthesis and characterization of polyaniline/ carbon black porous composites

WANG Hai-yan1,DAND Zhi-min2,KONG Ling-bin1,SONG Hui-qin1(1.State Key Laboratory of Gansu Advanced Non-ferrous Metal Materials, Lanzhou University of Technology,Lanzhou 730050,China; 2.Department of Polymer Science and Engineering,School of Chemistry and Biological Engineering, University of Science & Technology Beijing,Beijing 100083,China)  
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℃.
