Abstract

Chitosan-g-polyvinyl acetate (Cs-g-PVAc) was synthesized successfully using redox copolymerization using potassium persulfate as initiator. TiO and TiO doped ZnO which previously prepared by sol-gel technique added for preparing emulsion from polymer - metal oxide nanocomposites. Cotton fabrics were treated with prepared emulsions using citric acid and sodium hypophosphite. XRD measurements prove that the prepared TiO nanoparticles corresponded to anatase phase with average crystallite size d = 15.98 nm where the crystallinity and crystallite size decreased for Zn doped TiO where d = 11.7 nm. FTIR indicates that the exhibition of grafting process and formation polymer metal oxide nanocomposite. Samples treated with Copolymer showed the highest antibacterial properties. However, the copolymer doped with TiO and TiO/ZnO showed lowest contact angle and affects positively on its photocatalytic performance. SEM and TEM micrographs confirmed that the prepared metal oxides are in nano scales, where TiO is smaller than TiO/ZnO which effects on the band gap of TiO/ZnO to be larger than TiO and consequently decreased on the photocatalytic properties TiO/ZnO of samples compared to TiO sample under the halogen lamp.
