含木质素的纳米纤维素/聚吡咯复合膜的制备及其电容性能研究
Preparation and Capacitive Performance Study of the Lignin-containing Cellulose Nanofibril/Polypyrrole Composite Film
摘要
Abstract
In this study,lignin-containing cellulose nanofibril(LCNF)was prepared using poplar chemi-mechanical pulp as the raw mate-rial,which was sequentially subjected to 2,2,6,6-tetramethylpiperidine-N-oxide(TEMPO)radical oxidation,high-shear treatment and high-pressure homogenization.The LCNF was then used as a flexible substrate to prepare LCNF/polypyrrole(LNP)composite film elec-trodes.Furthermore,the effects of TEMPO oxidation degree on the residual lignin content,yield and morphology of LCNF,as well as on the microstructure of LNP composite film were investigated,and the structure-activity relationship between LNP structure and capaci-tance performance was analyzed.The results showed that as the degree of TEMPO oxidation increased,the lignin content and size of the LCNF decreased gradually.The morphology of LCNF and LNP composite film could be altered by the lignin through the regulation of fi-brillation.This could further affect the microstructure of LNP composite film through adhesion,thereby improving its capacitance perfor-mance.In addition,lignin could also provide pseudocapacitance of LNP composite film via the reversible conversion of the quinone/hy-droquinone structure.Moreover,the supercapacitor assembled with the LNP-13.8%composite film exhibited a power density of 499.9 µW/cm² and an energy density of 88.6 µWh/cm²,demonstrating excellent energy storage capability.关键词
