Abstract

Bioplastics have garnered significant attention as sustainable alternatives to conventional petroleum-based plastics, primarily due to their potential to reduce ecological footprints and enhance biodegradability. Among various bioplastics, copolymer-based systems exhibit unique properties resulting from the interplay of their constituent monomers. This article provides a comprehensive analysis of the structure-property relationships inherent in copolymer-based bioplastics, focusing on how variations in chemical composition, molecular structure, and processing conditions influence mechanical performance. Emphasis is placed on common copolymers such as poly(lactic acid) (PLA), polyhydroxyalkanoates (PHA), and their blends with other biopolymers. The findings outlined herein aim to guide material scientists and engineers in the efficient design and application of copolymer-based bioplastics for various industrial applications.
