Description

technical field [0001] The invention relates to a polymer material, in particular to a PHB composite material and a preparation method thereof. Background technique [0002] Polyhydroxybutyrate PHB is a natural polymer with special properties such as biocompatibility, biodegradability, non-irritation, non-immunogenicity and tissue compatibility. It is used in tissue engineering, drug sustained release Successful applications have been achieved in the fields of controlled release systems, orthopedics, and medical surgical sutures. PHB has good biodegradability, and its decomposition products can all be used biologically without any pollution to the environment. Its physical properties and molecular structure are very similar to polypropylene, such as molar mass, softening point, crystallinity, tensile strength, etc. It is currently mainly used in medical, industrial, packaging, agricultural and other fields. [0003] For example, patent application CN201210061825.5 provides...
