| Abstract |
In this research, natural rubber (NR)-TiO2 nanocomposites were developed for triboelectric
nanogenerator (TENG) application to harvest mechanical energy into electrical energy. Rutile TiO2
nanoparticles were used as fillers in NR material to improve dielectric properties so as to enhance
the energy conversion performance of the NR composite TENG. The effect of filler concentration on
TENG performance of the NR-TiO2 composites was investigated. In addition, ball-milling method
was employed to reduce the agglomeration of TiO2 nanoparticles in order to improve their dispersion
in the NR film. It was found that the TENG performance was significantly enhanced due to the
increased dielectric constant of the NR-TiO2 composite films fabricated from the ball-milled TiO2
.
The TENG, fabricated from the NR-TiO2 composite using 24 h ball-milled TiO2 at 0.5%wt, delivered
the highest power density of 237 mW/m2
, which was almost four times higher than that of pristine
NR TENG. Furthermore, the applications of the fabricated NR-TiO2 TENG as a power source to
operate portable electronics devices were also demonstrated. |
