Preparation And Characterization Of Poly(3-Hydroxybutyrate-Co-3- Hydroxyhexanoate) Reinforced Kenaf Fibre

Polyhydroxyalkanoate (PHA) is an advantageous polymeric material due to environmental friendliness but its mechanical properties limits its potential in material selection. Green composites, produced from renewable polymers such as thermoplastic PHA and natural fibres, are possible ways to solve...
