Poly(3-hydroxybutyrate)‎ and Poly(3-hydroxybutyrate-co-3-hydroxyvalerate)‎: Structure, Property, and Fiber

الملخص EN

Poly(3-hydroxybutyrate) [P(3HB)] and poly(3-hydroxybutyrate-co-3-hydroxyvalerate) [P(3HB-co-3HV)] are produced by various microorganisms as an intracellular carbon and energy reserve from agricultural feedstocks such as sugars and plant oils under unbalanced growth conditions.

P(3HB) and P(3HB-co-3HV) have attracted the attention of academia and industry because of its biodegradability, biocompatibility, thermoplasticity, and plastic-like properties.

This review first introduced the isodimorphism, spherulites, and molecular interaction of P(3HB) and P(3HB-co-3HV).

In addition, the effects of 3HV content on the melting temperature and crystallization rate were discussed.

Then the drawbacks of P(3HB) and P(3HB-co-3HV) including brittleness, narrow melt processing window, low crystallization rate, slow biodegradation rate in body, and so on were summarized.

At last, the preparation, structure, and properties of P(3HB) and P(3HB-co-3HV) fiber were introduced.
