A comparative study on the chitosan membranes prepared from glycine hydrochloride and acetic acid

► Gly·HCl is a promising solvent to prepare regenerated chitosan membrane (CSM). ► The prepared CSM presents a novel structure and superior mechanical performance. ► The chitosan microporous membranes (CSMMs) were prepared using PEG as porogen. ► The morphology of CSMMs prepared from Gly·HCl and acetic acid is different.
