Efficiency of the novel TP/LLDPE nanocomposite in killing multi-drug resistant pathogens

A series of linear low-density polyethylene (LLDPE) polymer nanocomposites with g-C3N4-ZnO/TiO2 ternary photocatalyst (TP) at 1 wt%, 5 wt%,7 wt%, and 10 wt% was synthesised by melt blending method. The structural properties, chemical properties, photocatalytic and antibacterial activities were evaluated in this study. The addition of TP reduces the degree of crystallisation of the LLDPE nanocomposite. The OH functional group on TP increases the polarity, thus improving the LB broth's wettability for bacterial adhesion, which enhances the inactivation effect. A minimum of 0.3 mg l(-1) of Zn2+ together with (OH)-O-center dot and (center dot) O2- O2- 99% inactivation against the MDR pathogens within 12 h while with 5 wt%, it takes 6 h. The synergic action of structural properties such as crystallinity, wettability, chemical structure on the reactive oxygen species (ROS), and Zn ion release for inactivation against the MDR pathogens is deliberated.
