Abstract

Kesan saiz butiran / partikel yang berbeza dan pengubahsuaian permukaan melalui penyepuhlindapan haba, struktur elektrik, dan sifat optik daripada cakera ZnO tulen dan koposit (varistor) yang difabrikasi daripada mikro atau nanopartikel ZnO dikaji dalam kajian ini berhubung dengan ketoksikan mereka. Empat sampel ZnO dengan saiz berbeza iaitu ZnO-White, ZnO-Pharma, 40mm ZnO dan 20mm-ZnO dicirikan. The effects of different particle/grain sizes and surface modification by thermal annealing process on the structural, electrical, and optical characteristics of pure and composite (varistors) ZnO discs fabricated from ZnO micro or nanoparticles were investigated in this study with respect to their toxicity. Four ZnO powder samples with different particle sizes namely ZnO-White (130 nm), ZnO-Pharma (80 nm), 40nm-ZnO and 20nm-ZnO were characterized.
