摘要:为解决聚苯胺在纤维素纤维表面易团聚及负载量低的问题,本研究以锆-单宁超分子配位聚合物对纤维进行改性,通过调控苯胺单体的原位聚合过程,在纤维表面成功制备了高负载量的纳米网络结构聚苯胺。结果表明,通过锆-单宁超分子配位聚合物改性,聚苯胺在纤维素纤维上的沉积率高达34.45%,复合材料的电导率达22.73 S/m。电化学测试结果显示,所制备的复合纸基电极在2 mA/cm²的电流密度下,面积比电容高达2 947 mF/cm²。将该电极材料组装成对称超级电容器,其在95.47 mW/cm3的功率密度下,能量密度可达33.55 mWh/cm³。
Abstract:To address the problems of easy agglomeration and low loading of polyaniline on the surface of cellulose fibers, this study used a zirconium-tannin supramolecular coordination polymer to modify the fibers, thereby regulating the in-situ polymerization of aniline monomers and successfully preparing a high-loading nano-network structure of polyaniline on the fiber surface. The results showed that through modification with the zirconium-tannin supramolecular coordination polymer, the deposition rate of polyaniline on the cellulose fibers reached as high as 34.45%, and the electrical conductivity of the composite material reached 22.73 S/m. Electrochemical test results revealed that the prepared composite paper-based electrode achieved an area-specific capacitance of up to 2 947 mF/cm² at a current density of 2 mA/cm². When this electrode material was assembled into a symmetric supercapacitor, it could achieve an energy density of 33.55 mWh/cm³ at a power density of 95.47 mW/cm³.
