NOVELTY - Aramid nanofiber hybrid film comprises 100 pts. wt. aramid nanofibers, and 3-15 pts. wt. graphene oxide. USE - Used as aramid nanofiber hybrid film. ADVANTAGE - The nanofiber hybrid film has high mechanical property and mechanical strength. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for preparing aramid nanofiber hybrid film comprising (i) blending dimethyl sulfoxide dispersion of graphene oxide with dimethyl sulfoxide solution of the aramid nanofiber, and stirring at room temperature for more than 1 hour, where in the blend liquid, the amount of aramid nanofiber is 100 pts. wt., and the graphene oxide is 3-15 pts. wt., (ii) adding deionized water into the blending liquid, stirring at room temperature for more than 2 hours, and then aging for 2 hours at room temperature, (iii) removing solvent by vacuum filtration to obtain gelatinous graphene oxide/aramid nanofiber composite material, drying at room temperature, peeling off from the microporous membrane, and vacuum drying for 6 hours to obtain aramid nanofiber hybrid film.
