Improving the Mechanical Properties of Biodegradable Polyhydroxyalkanoates via PHA–PHA Block‐Copolymer Synthesis

Chemistry – A European Journal, EarlyView.
Covalent linkage of a highly crystalline PHBV with a ductile P3HB4HB is shown to produce block copolymers with markedly enhanced extensibility and toughness, outperforming equivalent blends. The results demonstrate that polymer architecture, not composition alone, governs mechanical response, offering a route to biodegradable materials that combine ...

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.
