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 ...

Study of the Biodegradation Properties of Amorphous Blends of Poly(Lactic Acid) and Poly(3‐Hydroxybutyrate‐co‐4‐Hydroxybutyrate) Foamed With Supercritical CO2

Macromolecular Materials and Engineering, Volume 311, Issue 8, August 2026.
Supercritical CO2 foaming of fully amorphous PLA/PHA blends produced low‐density closed‐cell foams with fine cellular morphology. Blending with PHA enhanced biodegradation under simulated home‐composting conditions, achieving up to 84% mass loss after 4 months, whereas marine degradation remained limited and was mainly restricted to the PHA component ...

In Vitro Biological Evaluation of Fibrous PHBV Polymer and CHA/PHBV Nanocomposite Scaffolds Developed for Tissue Engineering Applications

Bioceramics Development and Applications, 2011
In recent years, a variety of fibrous bioactive bioceramic-polymer composite scaffolds were made through electrospinning and their usefulness for bone tissue engineering was investigated. In this study, nanospheres of carbonated hydroxyapatite (CHA), which is a proven osteoconductive and biodegradable bioceramic, were synthesized using a nanoemulsion ...

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, Volume 66, Issue 8, Page 5685-5700, August 2026.
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 ...
