Question

what are properties of PHB

and

Elaborate of PHA

Answer 1

Explanation:

PHB is a fully biodegradable polyester with optical activity, piezoelectricity, and very good barrier properties [6,8]. PHB is a partially crystalline material with a high melting temperature and a high degree of crystallinity. PHB is a thermoplastic, belonging to the family of polyhydroxyalkanoate PHAs.

Answer 2

Answer:

PHAs are soluble in halogenated solvents such chloroform, dichloromethane or dichloroethane. PHB is similar in its material properties to polypropylene (PP), has a good resistance to moisture and aroma barrier properties. Polyhydroxybutyric acid synthesized from pure PHB is relatively brittle and stiff.
