PREPARATION OF METAL CONTAINING NANOCOMPOSITES BASED ON HIGH PRESSURE POLYETHYLENE AND RESEARCH INTO THEIR BACTERICIDAL PROPERTIES

Metal-containing nanocomposites based on high-density polyethylene (PE) were obtained by a mechanical-chemical method without using organic solvents by high-speed thermal decomposition of organic acid salts in terms of high shear deformations. The phase composition and structure of the obtained nanocomposites were studied by the method of X-ray phase analysis (XRD). XRD diffraction patterns confirm the presence of nanoparticles of zinc and copper oxides on the PE matrix. High antibacterial activity of zinc and copper-containing nanocomposites in respect of gram positive and gram-negative bacteria was revealed: Aspergillus niger, A. ochraseus, Penicillium cuclopium, Cladosporium herbarium, Fusarium moniliforme and F.oxysporium. This testifies to the possibility of their use as antimicrobial additives for purifying drinking water from harmful microbes, as well as additives to plastics for imparting bactericidal properties.
