金属离子掺杂-浸渍聚合法制备聚苯胺/纤维素基导电材料OA

In this study,using bamboo pulp cellulose as a flexible scaffold and aniline and ammonium persulfate as raw materials for polym-erization,the chelating effect of cellulose on metal ions(Fe3+,Cu2+,Co2+,Mn2+,Zn2+)was utilized to promote the uniform polymerization of aniline within the fiber network.A stepwise loading strategy was adopted,based on in-situ polymerization involving secondary impregnation polymerization of aniline monomers,to precisely control the deposition morphology and conductive network.The PANI/cellulose-based con-ductive material was characterized in terms of conductivity,mechanical properties,and electrochemical performance.The results showed that the PANI/cellulose-based conductive material exhibited a significant increase in conductivity from 0.12 S/cm of reference bamboo paper to 1.55 S/cm,a tensile index of 8.70 N·m/g,and a high areal specific capacitance of 5 639 mF/cm² at a current density of 1 mA/cm².The material combined high conductivity,good mechanical properties,and excellent electrochemical performance,making it suitable for appli-cation in flexible supercapacitor electrodes.
