Abstract

Biopolymer blends have emerged as a promising avenue for developing sustainable materials with enhanced properties tailored for diverse applications. This study explores the synergistic effects that arise from blending different biopolymers, focusing on their ability to improve mechanical strength, thermal stability, and barrier properties. Key compatibilization techniques, such as the use of plasticizers, cross-linking agents, and nanofillers, are reviewed to highlight their role in optimizing interfacial interactions between blend components. Emphasis is placed on recent advancements in biopolymer blends for applications in packaging, biomedical devices, and structural materials. Additionally, the environmental implications of biopolymer blends are discussed, underlining their potential to reduce plastic waste and carbon footprints. This work provides a comprehensive overview of the mechanisms driving synergistic effects in biopolymer blends, paving the way for innovative materials with superior performance and durability.
