Polyhydroxyalkanoates (PHAs), their Blends, Composites and Nanocomposites: State of the Art, New Challenges and Opportunities

Polyhydroxyalkanoates are very promising biomaterials in nature. The bio-based materials have tremendous applications in almost all areas of human life. The present chapter deals with a brief account on polyhydroxyalkanoates and their structure and properties, blends, composites and nanocomposites. Different synthesising, preparation, and characterisation methods of polyhydroxyalkanoate-based blends, composites and nanocomposites are discussed. Finally, the applications, new challenges and opportunities for these polyhydroxyalkanoate-based blends, composites and nanocomposites are discussed.
