Multilayer Chitin–Chitosan–Cellulose Barrier Coatings on Poly(ethylene terephthalate)
Journal: ACS Applied Polymer Materials
Year: 2022

Currently, effective barrier properties over a wide range of humidity are achieved by layering multiple plastics, resulting in structures that are nearly impossible to recycle through current systems. There is strong interest in developing barriers that are recyclable, biodegradable, or compostable. Chitin and cellulose nanomaterials are promising alternatives because of their high crystallinity, renewable sourcing, strong electrostatic interactions, and potential for biodegradation or compostin
