T
o 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.

Biography
Wen-Rong Xu has her expertise in chitin biomass conversion and applications, as well as organic synthesis and supramolecular chemistry. Her research group
has successfully converted the chitin biomass into polyols through the simple and effective liquefaction method, and the resulting polyols were further used for the
polymer modification. This research has opened a new way for the high-value added use of fishing industrial wastes.
