Bionanocomposite based on cellulose nanowhisker from oil palm biomass-filled poly(lactic acid)

Cellulose nanowhiskers (CNW) extracted from plant fibers exhibit remarkable properties that make them suitable for use in the development of bionanocomposites. CNW have demonstrated the capability to enhance the properties of a polymer matrix at low filler loading. In this study, poly (lactic acid)...
