Preparation of hydrogel containing chitosan and virgin coconut oil using the freeze-thawing method

Abstract

This study aimed to formulate a hydrogel membrane containing chitosan (CS) and virgin coconut oil (VCO) using repeated cycles of freezing and thawing (F-T) for wound dressing applications. This study evaluated the effects of degree of hydrolysis of polyvinyl alcohol (PVA), solution concentration and thickness, number of F-T cycles, CS proportion on the sensory properties, swelling ratio, and gel fraction of hydrogels...
