“Soft-rigid” synergistic reinforcement of PHBV composites with functionalized cellulose nanocrystals and amorphous recycled polycarbonate

, 2021
Herein, both rigid cellulose nanocrystal with photoactive groups (CNC-Cc) and amorphous polycarbonate (extracted from discarded CD) were functionalized as reinforcing agents to obtain poly(3-hydroxybutyrate-co-3-hydroxyvalerate)/polycarbonate/CNC-Cc ...

Antibiotic Release from Biodegradable PHBV Microparticles

Journal of Controlled Release, 1998
For the treatment of periodontal diseases, design of a controlled release system seemed very appropriate for an effective, long term result. In this study a novel, biodegradable microbial polyester, poly(3-hydroxybutyrate-co-3-hydroxyvalerate), PHBV of various valerate contents containing a well established antibiotic, tetracycline, known to be ...

Improvement in hydrophilicity of PHBV films by plasma treatment

Journal of Biomedical Materials Research Part A, 2005
AbstractPoly(3‐hydroxybutyrate‐co‐hydroxyvalerate) (PHBV) films were prepared by the solvent cast method. Oxygen and nitrogen plasma treatment were used to improve the hydrophilicity of the surface of PHBV films. The surface properties were characterized by contact angle measurement and X‐ray photoelectron spectroscopy (XPS). The water contact angle of

Tissue engineered cartilage on collagen and PHBV matrices

Biomaterials, 2005
Cartilage engineering is a very novel approach to tissue repair through use of implants. Matrices of collagen containing calcium phosphate (CaP-Gelfix), and matrices of poly(3-hydroxybutyric acid-co-3-hydroxyvaleric acid) (PHBV) were produced to create a cartilage via tissue engineering.

Interaction of human smooth muscle cells on random and aligned nanofibrous scaffolds of PHBV and PHBV-gelatin

International Journal of Polymeric Materials and Polymeric Biomaterials, 2016
ABSTRACTTissue-engineered scaffolds with nanofibrous morphology have been shown to be effective in regeneration of tissues because nanofibers mimic the native architecture of the extracellular matrix. The unique alignment in the native tissue motivated the authors to fabricate aligned nanofibers of poly(3-hydroxybutyrate-co-3-hydroxyvalerate) (PHBV ...

Fabrication and Characterization of Bioactive Wollastonite/PHBV Composite Scaffolds

Biomaterials, 2004
Composite scaffolds of polyhydroxybutyrate-polyhydroxyvalerate (PHBV) with bioactive wollastonite were fabricated by a compression moulding, thermal processing, and salt particulate leaching method. Structure and mechanical properties of the scaffolds were determined. The bioactivity of the composites was evaluated by soaking in a simulated body fluid (

Reactive extrusion of sustainable PHBV/PBAT-based nanocomposite films with organically modified nanoclay for packaging applications: Compression moulding vs. cast film extrusion

, 2020
The mechanical, thermal and barrier properties of a sustainable PHBV/PBAT blend was investigated under the influence of organically modified nanoclay (0.6, 1.2 and 1.8 wt%) after processing by two different techniques i.e.
