Effect of Plasticisers and Zinc Oxide Nanoparticle Concentration on the Properties of Polyethylene Thin Films

The present work describes the preparation of a polyethylene film covered with a protective layer of zinc oxide nanoparticles (ZnO NPs). The presence of ZnO NPs on a slide supplemented with polyethylene was confirmed by the appearance of white cloud-like spots. Various ZnO NP concentrations were examined for their impact on optical and physical properties and in terms of inhibiting the growth of bacteria that can cause excessive irritation or intolerable skin sensitivity in the long term. This newly developed film holds potential for use in baby diapers to reduce bacterial contamination.
