Antibacterial properties of polyeugenol/ZnO composite material.

Research about the manufacture of polyeugenol/ZnO composite materials was carried out with ratios: 100:0 75:25 50:50 25:75 and 0:100 (w/w; mg/mg). Polyeugenol was synthesized from eugenol compound using H2SO4-CH3COOH catalyst. The addition of ZnO could show much stronger antibacterial properties compared to polyeugenol. The reason for this research was to decide the proportion of the polyeugenol/ZnO composite material which has the most grounded antibacterial action against Escherichia coli and Staphylococcus aureus microorganisms. The strategy for deciding antibacterial properties was a good dissemination technique by noticing the distance across the restraint zone. The data obtained were analyzed through variance methods (ANOVA) and post-hoc tests by Duncan. The comparison showed the largest inhibition zone diameter of 19.76 mm for S.aureus and 20.29 mm for E.coli (polyeugenol 75 mg : ZnO 25 mg). [ABSTRACT FROM AUTHOR]
