Nanocellulose from Unbleached Hemp Fibers as a Filler for Biobased Photocured Composites with Epoxidized Cardanol

Biobased composites were successfully prepared using raw materials derived from biomass waste, i.e., an epoxy resin obtained cardanol and nanocellulose unbleached hemp fibers. The by solvent exchange impregnation of the cellulosic mat with resin, followed photocuring. Quantitative conversion was obtained, despite high amount fibers (30 wt%) their absorbance in UV region light spectrum. X-ray diffraction confirmed that crystalline structure cellulose did not change during curing process. cured flexible, hydrophobic, water resistant, transparent a yellow/brown color, rubbery state at room temperature.
