Abstract

ABSTRACTSol-gel and melt-mixing processes, which are used for the synthesis of low-density polyethylene/silver/titanium dioxide nanocomposites, can inactivate pathogens. In the sol-gel method, the nanocomposites were used to treat four selected microorganisms using the disk-diffusion method. In the melt-mixing method, fish coverage films were used to examine the shelf life of fish. TiO2 along with different concentrations of Ag (0%, 1%, 3%, and 5%) generated the nanocomposites. The maximum inhibition zone diameters (mm) for Staphylococcus aureus, Escherichia coli, Candida albicans, and Aspergillus niger in 3% Ag were measured. It was concluded that applying the LDPE/Ag/TiO2 nanocomposites produced could be beneficial for inactivation of pathogens.
