Tensile Strength of PHBV/Natural Rubber Latex Mixtures

MATEC Web of Conferences, 2015
A polyhydroxybutyrate-co-hydroxyvalerate (PHBV) is mingled with natural rubber latex (R) to develop its mechanical property of the blend. Normally, substantial effects of the PHBV are hard, fragile, and inelastic, whereas the natural rubber is ...

Compatibilization and Reinforcement of PHB/PBAT Blends via Sequential Blending of Surface‐Modified Cellulose

Polymer Engineering &Science, EarlyView.
Sequential blending improved the mechancial properties of PHB/PBAT/cellulose composites as compared to the one‐step batch mixing method. ABSTRACT Polyhydroxybutyrate (PHB) is a natural and biodegradable polymer generated by bacteria. While its applications to potentially replace petroleum‐based plastics are severely limited due to its brittleness and ...

Melt and Cold Crystallization Behavior of Poly(Lactic Acid) With Different Molecular Weights and Its Influence on Mechanical, Viscoelastic, and Tribological Properties

Polymer Engineering &Science, EarlyView.
Modifying the crystallinity of PLA and its properties through annealing. ABSTRACT The melt and cold crystallization behavior of two PLA grades with different molecular weights was investigated using various DSC analyses. During isothermal melt crystallization, PLA with lower molecular weight exhibited faster crystallization kinetics across different ...

Tunable Natural Deep Eutectic Solvents‐Driven Fractionation of Olive Pomace in an Integrated Biorefinery: Linking Lignin Structural Tailoring to Carbohydrate Valorization and Biopolymer Production

ChemSusChem, Volume 19, Issue 13, 14 July 2026.
Microwave‐conditioned olive pomace was fractionated with deep eutectic solvents (DESs) spanning acidic, neutral, alkaline, and chemo‐enzymatic regimes. The alkaline DES provided the best balance between delignification and carbohydrate preservation, yielding a fermentable glucose/xylose stream suitable for Haloferax mediterranei fermentation and poly(3‐
