Development of Bilayer Biodegradable Composites Containing Cellulose Nanocrystals with Antioxidant Properties

The interest in the development of novel biodegradable composites has increased over last years, and multilayer composites allow the design of materials with functionality and improved properties. In this work, bilayer structures based on a coated zein layer containing quercetin and cellulose nanocr...
