Abstract

To expand the applications of fishing industrial wastes, the liquefaction technique was employed to convert chitin and shrimp shells into liquids, which were first further used to for the modification of polymer materials. Ball-mill treated chitin and shrimp shells were effectively liquefied into polyols, namely LBMC and LBMS, respectively, by liquefaction technique. FTIR, NMR and GPC analyses of liquefied products turned out that depolymerization and deacetylation reactions occurred during liquefaction process. LBMC/PVA and LBMS/PVA blend membranes with various LBMC or LBMS content were prepared and characterized by FTIR and SEM investigation. In addition, tensile strength, elongation at break, water content, degradation and antibacterial properties were thoroughly discussed. The mechanical property and thermal stability were greatly enhanced under the optimal optimized conditions of 0.6 wt% incorporation of liquefied chitin incorporation to PVA. In particular, the antibacterial activity was obviously improved after the incorporation of LBMC or LBMS. Recent Publications 1.
