Several researchers extracted CNF from agricultural sources to produce nanopapers. CNF from empty palm fruit bunch (EPFB) could be a good candidate for high performance applications of nanopaper having similar strength and structure of wood CNF. Nanopapers from EPFB-CNF had high modulus (1218 GPa) and tensile strength (103137 MPa) as well as low water absorptionrate [243]. Hassan and Mathew [244] compared the opacity, tensile strength, and porosity of a nanopaper made of CNF from bagasse with other made from rice straw through refining and homogenization processes. Both nanopapers showed lower porosity when compared to paper sheets produced from original pulps. Nanopaper made from bagasse-CNF exhibited better dry and wet tensile strength compared to those prepared from rice straw- CNF. The presence of silica in the rice straw nanopaper decreased the tensile strength and transparency compared to those of bagasse-CNF sheets.
