Description
Hyun-woo Lee, Hayeong Lee, and Keon-Soo Jang improve a plant-based plastic by blending in a flexible polymer and mica flakes in this 2025 paper. The base plastic, PLA, is brittle and heat-sensitive, which limits its use. The blend partner, PVB, carries hydroxyl groups that grip mica well.
Five mica grades were tested in plain and blended mixes. In plain PLA the flakes dispersed poorly and strength fell. With PVB present, dispersion evened out and tensile strength and toughness rose. Mica also stiffened the glass transition, while some grades cut chains during processing and raised flow. Rheology showed thicker melts from stronger molecular interaction. The authors call the pairing a promising route to tougher sustainable materials.
