The morphology of crystallisation of PHBV/PHBV copolymer blends [PDF]
European Polymer Journal, 2019 The crystallisation of a range of as-produced poly(3-hydroxybutyrate-co-3-hydroxyvalerate) copolymer blends from a mixed culture polyhydroxyalkanoate production process, with low (15%), high (82%) and intermediate (62% and 50%) average 3-hydroxyvalerate (3HV) contents, was studied at different temperatures using polarised optical microscopy ...

Quercetin modified electrospun PHBV fibrous scaffold enhances cartilage regeneration
Journal of Materials Science: Materials in Medicine, 2021 It suggests that the poly (3-hydroxybutyric acid-co-3-hydroxyvaleric acid) (PHBV) scaffold can be used for cartilage tissue engineering, but PHBV is short of bioactivity that is required for cartilage regeneration.

Film blowing of PHBV blends and PHBV‐based multilayers for the production of biodegradable packages [PDF]
Journal of Applied Polymer Science, 2015 ABSTRACT Poly(hydroxy butyrate ‐co‐ valerate) (PHBV) is a biodegradable polymer that is difficult to melt process into films. Such difficulty is mirrored in the lack of literature on film blowing of PHBV‐ or PHBV‐based materials. To circumvent this problem, 70/30 wt % blends
