STUDY ON BIODEGRADABLE AND ANTIMICROBIAL PROPERTIES OF BIOWASTE CHITIN-POLYVINYL ALCOHOL BLENDED FILM

The film forming ability of chitin (CT) blended with polyvinyl alcohol (PVA) were prepared a seriesof nine different ratios CT:PVA, (10:90, 20:80, 30:70, 40:60, 50:50, 60:40, 70:30, 80:20, 90:10v/v),using 2% solution and 10% solution. All films have highlytransparent, smooth surface pale-yellow color. characterized by usingthe physical parameters, the physico-mechanical properties, degree swelling, water uptake. Asmeasured swelling uptake, showed higher hydration, as aresult varying weight percent PVA in membrane matrix. Comparative characterization theprepared included FT IR TG-DTA analysis. From analysis, characteristicabsorption peaks CT-PVA clearly that two polymers well mixed.According to thermal stability was found be slightlylower. various types also tested for antimicrobial activity using anagar disc diffusion method. these results, all showedpronounce activities. Subsequently, biodegradable nature CT-PVAblended studied through soil burial test. Finally, can beused wound dressing, packaging materials.
