Ultrasonic spray deposition of PEGDE-crosslinked chitosan/graphene oxide coatings for enhancing gas barrier properties of polybutylene succinate films

Biobased and biodegradable polymers represent a valid and sustainable alternative to oil-based plastics, as they are renewable and address the issue related to the end-of-life of non-compostable materials. However, the poor gas barrier of biopolymers limits their use in several applications, including food packaging.
