Shear Piezoelectricity in Poly(L‐Lactic Acid): From Molecular Chirality to Regenerative Materials Design

Small Structures, Volume 7, Issue 7, July 2026.
This review highlights how PLLA's molecular chirality and noncentrosymmetric chain packing generate intrinsic shear piezoelectricity without electrical poling, while crystallinity, optical purity, and molecular orientation define its design space. By distinguishing intrinsic d14 from device‐level outputs and connecting processing strategies to tissue ...

Thermal depolymerization mechanisms of poly(3-hydroxybutyrate-co-3-hydroxyvalerate)

Progress in Natural Science: Materials International, 2016
AbstractThermal degradation processes and decomposition mechanisms of poly(3-hydroxybutyrate-co-3-hydroxyvalerate) (PHBV) were investigated by using thermal gravity analysis(TGA), Gel permeation chromatography (GPC), elemental analyzer, pyrolysis-gas chromatography-mass spectrometry (PyGC-MS) and 1H nuclear magnetic resonance (1H NMR).

On the Mechanical and Thermal Behavior of PLA, PBAT, and PHBV‐Based Ternary Blends and the Effect of Short Flax Fibers as Reinforcing Agents

Polymer Composites, Volume 47, Issue 12, Page 11409-11428, 20 June 2026.
Preparation and testing of biodegradable polymer ternary blends and composites with short flax fibres. ABSTRACT Bioplastics offer environmental benefits but they are costly and exhibit lower mechanical and thermal performance compared to fossil‐based counterparts. Poly(butylene adipate‐co‐terephthalate) (PBAT) exhibits high ductility but relatively low
