Improving biological production of poly(3-hydroxybutyrate-co-3-hydroxyvalerate) (PHBV) co-polymer: a critical review

Reviews in Environmental Science and Bio\/technology, 2021
Although poly(3-hydroxybutyrate-co-3-hydroxyvalerate) (PHBV) is the most promising biopolymer for petroleum-based plastics replacement, the low processes productivity as well as the high sale price represent a major barrier for its widespread usage.

Non-Isothermal Crystallization Kinetics of Injection Grade PHBV and PHBV/Carbon Nanotubes Nanocomposites Using Isoconversional Method [PDF]

Journal of Composites Science, 2020
Carbon nanotubes (CNT)-reinforced polymeric composites are being studied as promising materials due to their enhanced properties. However, understanding the behavior of polymers during non-isothermal crystallization is important once the degree of crystallinity and crystallization processes are affected when nanoparticles are added to matrices. Usually,

Cartilage tissue engineering using PHBV and PHBV/Bioglass scaffolds

Molecular Medicine Reports, 2014
Scaffolds have an important role in cartilage tissue engineering. Poly(hydroxybutyrate‑co‑hydroxyvalerate) (PHBV) has been demonstrated to have potential as a scaffold for the three dimensional construction of engineered cartilage tissue. However, the poor hydrophilicity and mechanical strength associated with PHBV affects its clinical applications as ...
