Polyhydroxyalkanoates - Wikipedia

Polyhydroxyalkanoates are a popular class of bioplastics valued for their rapid biodegradadion, biocompatibility, and renewable feedstocks. While there are already a few commercial applications for these biopolymers, a greater diversity of properties is needed to compete with petroleum based polymers. In this chapter, we report the synthesis and characterization of polyhdroxyoctanoate and its nanocomposite with thermally reduced graphene. The results indicate the incorporation of graphene into the PHO matrix leads to a small upshift in the glass transition, enhance the thermal stability, and ∼600% increase in modulus. Electrical percolation between 0.5 and 1 vol.% TRG was obtained.

Plastic disposal is one of the greatest problems facing the environment today, as vast amounts of synthetic plastic remain non degradable. A number of microorganisms have the ability to degrade different types of plastic under suitable conditions, but due to the hardness of these polymers and their non-solubility in water, biological decomposition is a slow process. Natural plastics are made from plant and animal sources, or produced by a range of microorganisms, must be introduced. Some bacterial strains can produce and store bioplastics using carbon sources under suitable fermentation conditions. Such biomaterials are called polyhydroxyalkanoates (PHA) or biological polyester. They are safe, have no toxic by-products and can be degraded easily by microorganisms.
