| Abstract:In this study， using bamboo pulp cellulose as a flexible scaffold and aniline and ammonium persulfate as raw materials for polymerization， 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 conductive 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 application in flexible supercapacitor electrodes. |
