▎ 摘　　要

NOVELTY - A high mechanical strength aramid nanofiber/porous graphene/polyaniline composition comprises aramid fiber, porous graphene oxide and polyaniline in a weight ratio of 1:(0.02-0.2):(0.1-1). USE - High mechanical strength aramid nanofiber/porous graphene/polyaniline composition for preparing high mechanical strength aramid nanofiber/porous graphene/polyaniline film (claimed) useful for oil stain treatment and optical element technology application. ADVANTAGE - The high mechanical strength aramid nanofiber/porous graphene/polyaniline composition is reasonable in proportion, improves the mechanical strength of the hydrogel and oil absorbing ability of the aerogel. The film selects and absorbs visible light and exhibits excellent light transmittance and mechanical property. DETAILED DESCRIPTION - INDEPENDENT CLAIMS are included for the following: (1) a preparation method of high mechanical strength aramid nanofiber/porous graphene/polyaniline hydrogel, which involves (S1) dispersing aramid nanofiber, porous graphene oxide and polyaniline in high mechanical strength aramid nanofiber/porous graphene/polyaniline composition to obtain dispersion liquid, and (S2) subjecting the dispersion liquid to solvent exchange into glue and hydrothermal treatment; (2) application of high mechanical strength aramid nanofiber/porous graphene/polyaniline hydrogel in preparing high mechanical strength aramid nanofiber/porous graphene/polyaniline aerogel, which involves freezing and drying application of high mechanical strength aramid nanofiber/porous graphene/polyaniline hydrogel; and (3) a preparation method of high mechanical strength aramid nanofiber/porous graphene/polyaniline film, which involves uniformly mixing aramid fiber, porous graphene oxide and polyaniline in high mechanical strength aramid nanofiber/porous graphene/polyaniline composition to obtain dispersion liquid, coating the dispersion liquid on a mold sheet, exchanging the solvent into glue, performing hydrothermal treatment, and drying the obtained hydrogel film at low temperature.
