Effect of Multistage Deacetylation Conditions on Molecular Weight of Chitosan and Porosity of Prepared Scaffolds

Knowledge on the molecular weight and degree of deacetylation of its samples is essential for its applications and molecular weight is the main factor affecting properties ofchitosan [1]. This work focuses on reaching complete deacetylation without degrading the polymeric chain of chitosan during the process. In this study, a method was developed for chitosan preparation in order to control the molecular weight with high DD. Subsequently, a novel database is offered to prepare chitosan with different molecular weights and degrees of deacetylation through multistage trearment.
