Poly(3-hydroxybutyrate-Co-3-hydroxyvalerate) (PHBV) Based Biocomposites Containing Coffee Silverskin: Injection Moulding and Migration Performances Assessment

Chemical Engineering Transactions, 2022
Poly(3-hydroxybutyrate-co-3-hydroxyvalerate) (PHBV) is among the most attracting low environmental impact polymeric materials. Coffee Silverskin (CS), an agro-food residue, has been compounded in variable amounts into a PHBV matrix in the presence of ...

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, EarlyView.
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

Poly(Hydroxybutyrate‐Co‐Hydroxyvalerate)/Thermoplastic Starch Blends for Application in Biodegradable Mulch Films

Polymer Engineering &Science, EarlyView.
Poly(hydroxybutyrate‐co‐hydroxyvalerate)/thermoplastic starch blends, produced by melt processing, showed improvements in mechanical properties and water vapor transmission barrier performance, which can help control excessive water evaporation from the soil, thus contributing to pH and moisture regulation.

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 ...

Preparation and Characterization of PHBV/PCL-Diol Blend Films

Polymers, 2023
Biodegradable thin films based on poly(3-hydroxybutyrate-co-3-hydroxyvalerate) (PHBV) and poly(caprolactone diol) (PCL-diol) blend were developed using the solution casting method. PHBV is biodegradable, biocompatible, and produced naturally by bacterial activity, but its use is restricted by high crystallinity and low resistance to thermal degradation
