资源简介：
Nowadays, supercapacitors based on cellulose nanofibril (CNF) films have attracted extensive interest due to their excellent flexibility, light weight, and unique structure. Herein, we report that highly conductive films are prepared through polypyrrole(PPy) coating on CNF films by a simple and low-cost “soak and polymerization” method. The optimized flexible film features a high electrical conductivity of 23.77 S cm -1 , a superior tensile strength of 71.4 MPa, outstanding conductance stability, and a goodthermal stability.Additionally, the hybrid filmasa freestandingandbinder-free supercapacitorelectrode canprovide a high areal capacitance (2.26 F cm -2 at 2 mA cm -2) and good cyclic stability (a capacitance retention of 70.5% after 5000 cycles).
