چکیده مقاله:
In the present work a novel bio-nanocomposite polymeric material with enhanced photocatalytic antimicrobial activity and barrier properties has been designed and prepared via melt blending of low density polyethylene (LDPE) and hybridized system comprised of nano Tio2 and orgnoclay. The synergistic effects of silicate nano platelets upon the photoactivity of nanocomposite surface in killing E.coli and S.aureus bacteria have been investigated. Surface morphology of samples were studied by conducting surface tension measurements and Field-Emission (SEM), energy-dispersive-X ray analysis (EDXA), small angle X-ray diffractometery (SAXS) on the surface of samples. Linear melt-viscoelastic characterization exhibited improved dispersion for the both nanoparticles and enhanced barrier properties in interfacially compatibilized nanocomposite samples. Film blown nanocomposite based on Tio2/Clay hybrid system showed more potential for photo inactivation of E.coli bacteria under UV light irradiation as well as most reduced permeability compared to other samples.
