Fe(3)O(4)-Filled Cellulose Paper for Triboelectric Nanogenerator Application

Cellulose-based materials have recently drawn much interest due to their sustainability, biodegradability, biocompatibility, and low cost. In this present work, cellulose fiber paper (CFP) was fabricated from sugarcane leaves and used as a friction material for a triboelectric nanogenerator (TENG). Fe(3)O(4) was incorporated to CFP triboelectric material to increase the dielectric constant of CFP for boosting power generation of TENG. The Fe(3)O(4) filled CFP was synthesized using a facile one-pot co-precipitation technique. The effect of Fe(3)O(4) content in CFP on dielectric property and TENG performance was investigated and optimized. The CFP filled with Fe(3)O(4) nanoparticles exhibited the improved dielectric constant and possessed a superior TENG performance than pristine CF. The highest power density of 1.9 W/m(2) was achieved, which was able to charge commercial capacitors serving as a power source for small electronic devices.
