polyvinyl alcohol coating on polylactic acid scaffolds

Abstract one of the ways to modify the properties of polylactic acid scaffold is coating the surface with different materials. polyvinyl alcohol is one of the types of synthetic polymers, which is used for coating polylactic acid scaffolds due to its good properties such as high hydrophilicity, biocompatibility and biodegradability. this polymer is used in combination with other materials to cover the polylactic acid scaffold and plays the role of adhesive. in order to improve the properties of polylactic acid scaffold by coating it with polyvinyl alcohol by immersion method, it was found that this coating improves hydrophilicity and as a result increases cell adhesion and bioactivity.
