Chemical composition and structural characterization of Napier grass fibers

► Utilization of Napier grass fiber an important agricultural residue. ► Napier grass fibers could be suitable for making green composites. ► Physical properties and chemical composition of Napier grass fibers were studied. ► Alkali treated fibers have higher cellulose content than the untreated fiber. ► Napier fibers characterized by spectroscopy (FTIR, NMR) and morphology by SEM.
