Functional and Network PHAs via Stereoselective Polymerization and Tailored Post‐Transformation

Angewandte Chemie, Volume 138, Issue 36, 1 September 2026.
Catalyst‐controlled stereoselective (co)polymerization of functionalized lactones produces vinyl‐, allyl‐, and propargyl‐functionalized PHAs with high syndiotacticity and a broad applicable temperature window, which can be further transformed into crosslinked PHA thermosets, elastic supramolecular networks, and functional grafts. ABSTRACT Incorporation

Crystalline Poly(L‐Lactic Acid) Nanoparticles via Nonsolvent‐Induced Cascade Phase Separation

Journal of Polymer Science, EarlyView.
Water is used as the nonsolvent to induce liquid/liquid phase separation (LLPS) of poly(L‐lactic acid) (PLLA)/propylene carbonate solution and PLLA crystallization. Due to the two levels of cascade LLPS coupled with confined PLLA crystallization, three types of polymeric nanoparticles, including PLLA single crystals, Ouzo crystalsomes, and sheaf‐like ...

Citric Acid‐Crosslinked Chitosan Coatings Incorporating Curcumin for Enhancement of Antioxidant and Antimicrobial Properties

Journal of Vinyl and Additive Technology, EarlyView.
A fully bio‐based coating was developed using Chitosan, Citric acid, and Curcumin. Citric acid acts simultaneously as a green solvent and non‐toxic crosslinker. Dry Heat Treatment enhances water resistance and thermal stability, creating an active packaging system with dual antioxidant and antimicrobial properties to extend food shelf‐life.
