Polyhydroxybutyrate (PHB) is a polyester made by many microorganisms under conditions of nitrogen deficiency, and is produced commercially in bulk by biotechnology. It has been suggested that PHB-based materials (copolymers and composites) could be suitable for medical applications and may be biodegradable.

This paper reports the fabrication and characterization of three-dimensional, highly porous polyhydroxybutyrate (PHB), polyhydroxybutyrate-co-valerate (PHBV) and composite scaffolds made by the emulsion freezing / freezing-drying technique. Freeze-drying of the polymer/solvent/ water phase emulsions produced hard and tough scaffolds with interconnected

Crystallization behavior of polyhydroxybutyrate (PHB)
AIP Conference Proceedings, 2016Polyhydroxybutyrate (PHB) belongs to the family of polyhydroxyalkanoates and is both, biobased and biodegradable. Due to its linear chain structure, PHB is highly crystalline and has a melting temperature close to its decomposition temperature. Pure PHB crystallizes very slowly, so that the use for some technical applications is not commercially viable.

Polyhydroxybutyrate, Its Copolymers and Blends
Journal of Macromolecular Science, Part C: Polymer Reviews, 1995Abstract Polyhydroxybutyrate (PHB) is an optically active polymer of D(−)3-hydroxybutyric acid. It is a naturally occurring polymer produced by a wide variety of bacteria. It serves as an intracellular storage material for carbon and energy and is accumulated as granules within the cytoplasm [1–4] of the bacteria. The chemical structure of PHB is shown

Novel electrospun materials for bone tissue engineering were obtained by blending biodegradable polyhydroxybutyrate (PHB) or polyhydroxybutyrate valerate (PHBV) with the anionic sulfated polysaccharide κ-carrageenan (κ-CG) in varying ratios. In both systems, the two components phase separated as shown by FTIR, DSC and TGA.

Nanofibres from polyaniline/polyhydroxybutyrate blends
Synthetic Metals, 2009Three-dimensional nanofibres nonwoven webs were obtained from solution of poly(3-hydroxybutyric acid) (PHB) and dodecylbenzene sulfonic acid (DBSA) doped polyaniline in chlorophorm/trifluoroethanol mixture, using electrospinning method. The morphology, electro-active properties and supermolecular structure of nanofibres webs have been analyzed and ...

On Morphology of Polyhydroxybutyrate
2013It is in process installed, that to growth of polarity of dissolvent there is a perfection of a crystal structure and decrease of a share of amorphous phase polyhydroxybutyrate (PHB). It is shown, that a share of a defective crystal phase in films PHB directly proportional to magnitude of cohesive energy of dissolvent.
