Synthesis And Property Of Water Borne Polyurethane/Modified Nano-Zno Composites Packaging Membranes

Water borne polyurethane /modified nano-ZnO composites packaging membranes were synthesized from modified nano-ZnO, polybutyleneadipate glycol (PBA), polycaprolactone (PCL) isophorne diisocyanate (IPDI), dimethylol propionic acid (DMPA), ethylenediamine(EDA) by self-emulsified method. The phase property, mechanical, antibacterial and anti-ultraviolet properties of the composites packaging membranes influenced by the modified nano-ZnO content were studied by scanning electron microscopy (SEM), mechanical testing, and antibacterial testing. And the relative results were analysed.
