Polypyrrole/Sisal Fiber Composites for Energy Storage

摘要

Polypyrrole-based electrodes were fabricated for energy storage applications using sisal fibers as a substrate material. It was found that the PPy nanoparticles deposited on the surface of sisal fiber cellulose (SFC) connected to form a continuous sheath by taking along the microcrystalline cellulose template. The as-prepared nanocomposites demonstrated a mass-specific capacitance of 367 F/g at 200 mA/g current density in supercapacitor application. Moreover, SFC/PPy electrode retained about 57.8% of Cs retained when the current density increased five times. This work provides a straightforward method to utilize renewable resource sisal microcrystalline cellulose for conducting composite, which could apply in sensors, flexible electrodes, and flexible displays. It also opens a new field of potential applications of micrometre-scale natural microcrystalline cellulose.
