摘要
采用原位聚合法制备导电聚苯胺-四氧化三钴(PANI-Co3O4)复合材料。研究了Co3O4含量对复合材料电导率的影响。通过傅里叶红外光谱(FT-IR)、X射线衍射(XRD)、热失重法(TGA)和微分热失重法(DTG)等测试手段对复合材料的结构和性能进行了表征,并考察了复合材料在硫酸铜电解液体系中的电化学性能。结果表明:当mCo3O4:mAn=0.05时,PANI-Co3O4复合材料电导率最高为4.56 S/cm;PANI与Co3O4粒子之间存在着相互作用,适量Co3O4的加入能够提高PANI的热稳定性及在硫酸铜电解液体系中的催化活性和耐蚀性。
The conductive polyaniline-cobaltosic oxide（PANI-Co3O4） composites were synthesized by in-situ polymerization.The conductive composites with different contents of Co3O4 were studied.The structure and thermal stability of obtained composites were characterized by Fourier-transform infrared spectra（FT-IR）,X-ray diffraction（XRD）,thermogravimetry（TGA） and differential thermogravimetric（DTG）.The electrochemical characterization of composites were investigated in copper sulfate electrolyte solution.Results showed that the PANI-Co3O4 composites had the maximum conductivity of 4.56 S/cm under the condition of mCo3O4：mAn=0.05,and a strong interaction existed at the interface of PANI and Co3O4.Thermal stability of PANI-Co3O4 composite was higher than that of PANI.The catalytic activity and corrosion resistance of PANI with defined amount of Co3O4 in copper sulfate electrolyte solution could be improved.
