Chemical modification of palm kernel shell filled polylactic acid biocomposite flims

In this research the effect of untreated and treated palm kernel shell (PKS) on the mechanical properties, morphological analysis and thermal properties of polylactic acid (PLA)/PKS biocomposite films were studied. The biocomposite films from palm kernel shell powder and polylactic acid were prepar...
