Abstract
Bionanocomposites (BNCs) were prepared using sago starch (SS) based polymer embedded with nanorods zinc oxide (ZnO-N) as nanofiller. The percentage of ZnO-N was varied from 2 weight percent (wt %) to 10 wt % of total solid. Transmission electron microscope (TEM) and scanning electron microscope (SEM) were used to analyze the morphology and dispersion of ZnO-N in BNCs. Raman spectroscopy analysis showed the present of ZnO-N in BNCs not forming new chemical bonding instead a physical interaction occur between the nanofillers and BNCs. Current-field density behavior of BNCs in low voltage region showed nonlinear current-voltage behavior and the value of resistance increases as the applied voltage increases. Breakdown voltage has been achieved at field density in the range of 500 to 900V depends on the concentration of nanofiller.
