Both components are renewable and biodegradable, aiming to reduce reliance on petroleum-based plastics. The resulting semi-crystalline structures and strong intermolecular interactions indicate effective molecular-level compatibility, with MCC improving morphological uniformity and interfacial adhesion. Chitin enhances thermal stability and UV-blocking, while CH and MCC reduce water absorption, increase hydrophobicity, and improve tensile strength, Young’s modulus, and elongation at break.","cbCaiiKHEPTHjQOk","https://ap.wps.com/l/cbCaiiKHEPTHjQOk","pdf",2987055,7,1,26,"English","en","# Introduction\n## Plastic pollution and need for renewable materials\n## Biocomposite fabrication approaches and polymer choices\n## Rationale for PVA/chitin and PVA/MCC combinations\n# Study materials and film composition (PVA, chitin, MCC)\n# Physicochemical characterization (structure, UV blocking, water uptake)\n# Thermal and mechanical evaluation\n# Overall performance comparison of different compositions","[{\"question\":\"What renewable materials are used to reinforce PVA in the biocomposite films?\",\"answer\":\"The films use chitin extracted from shrimp shells and microcrystalline cellulose (MCC) extracted from alfa fibers as reinforcements in a PVA matrix.\"},{\"question\":\"How do chitin and MCC influence thermal stability and UV-blocking performance?\",\"answer\":\"Thermal analysis shows that chitin enhances thermal stability, and MCC strengthens this effect.
