Physicochemical and conductivity studies of chitosan-tapioca flour-LiBF4 gel polymer electrolytes

The present study emphasizes the isolation of chitin and chitosan from the exoskeleton of white shrimp, Fenneropenaeus indicus. Demineralization and deproteination were used to extract chitin, followed by deacetylation of the extracted chitin to yield chitosan. Chitin and chitosan were characterized...
