Abstract
To expand the applications of fishing industrial wastes, the liquefaction technique was employed to convert chitin into liquids, which were first further used for the modification of polymer materials. Ball-mill treated chitin was effectively liquefied into polyols in polyethylene glycol 400/glycerin mixed solvent. FTIR, 1H NMR and size exclusion chromatography analyses of liquefied chitin turned out that depolymerization and deacetylation reactions occurred during liquefaction process. The liquefied chitin/polyvinyl alcohol blend membranes with various mixing ratios were prepared and characterized by FTIR and SEM. In addition, transparency, tensile strength, elongation at break, water absorption, water retention and antibacterial properties were thoroughly discussed. The mechanical property and thermal stability were greatly enhanced under the optimized conditions of 25Â wt% liquefied chitin incorporation to polyvinyl alcohol. Moreover, the blend membranes showed improvements in water absorption and water retention capacity. In particular, the antibacterial activity was significantly improved after incorporation of liquefied chitin.
