A method using a combination of acid hydrolysis and ultrasonic homogenize were developed to obtain the CNF (cellulose nanofibers) from agave cantala fibers. Acid hydrolysis method able to produce the CNF with a diameter around of 45-50 nm, which can investigated by transmission electron microscopy (TEM). The homogenize mixing method between CNF 5 wt colloidal and 3 wt PVA (polyvinyl alcohol) with magnetic stirrer 350 RPM, at temperature of 50 oC, for 30 minutes followed by ultrasonic homogenizer has been causing CNF well distributed in the PVA matrix. PVA/CNF nanocomposites film was prepared by solution casting technique. Physical properties test by x-ray diffraction (XRD) and fourier transform infrared (FTIR) shows highly crystalline of CNF which indicates improvements the mechanical properties of PVA/CNF nanocomposite film. The tensile stress and elongation at break of PVA/CNF nanocomposite film were increased by 55 and 137 . © 2020 Trans Tech Publications Ltd, Switzerland.
