Summary

Researchers reinforced thermoplastic starch with icosahedral quasicrystal particles to address the poor mechanical and thermal performance that limits pure starch-based bioplastics, finding that the quasicrystal filler meaningfully improves composite properties while preserving the material's biodegradable and sustainable character.

Thermoplastic starch-based (TPS) composites represent a promising alternative to synthetic plastics due to their biodegradability and potential to address plastic waste pollution. However, pure TPS without additives or reinforcements lack sufficient mechanical, thermal, or functional propertie...
