In Situ Constructing Highly Aligned Ribbon-like PHBV Lamellae in PBAT: Towards Strong, Ductile and High-Barrier PBAT/PHBV Films
Despite its title referencing biodegradable plastic film materials (PBAT and PHBV), this paper studies the materials science of fabricating high-performance biodegradable packaging films — not microplastic pollution or health effects. It examines how combining two bio-based polymers with a compatibilizer improves mechanical strength and barrier properties and is not directly relevant to microplastic exposure or human health impacts.
