Improving water repellency, mechanical properties and antimicrobial activity of degradable plastics and papers with chitosan-based nanocomposite coating

Abstract

Degradable plastics and papers have emerged as a promising alternative to the environmental pollution caused by explosive usage of non-degradable materials. Despite its immense potential, their weak mechanical strength and premature degradation have prevented from more widespread usage. This study presents a comprehensive strategy of overcoming these issues by providing a protective surface coating with chitosan and chitosan-based composite. The multifunctional nature of chitosan allows substantial improvement in water repellency, mechanical properties, and antimicrobial properties of degradable plastics and papers, without compromising their bulk properties.
