Thermal behaviour of polylactic acid (PLA) nanocomposite based on modified nanoclay

Polylactic acid(PLA)has attracted much attention due to their biodegradability and biocompatibility properties. The organically modified montmorillonite or known as nanoclay namely Cloisite B30 (the montmorillonite modified with a quaternary ammonium salt) was used in this research. PLA nanocomposit...
