▎ 摘　　要

NOVELTY - Graphene fiber flame-retardant conductive non-woven fabric comprises 1-5 wt.% graphene conductive paste, 50-70 wt.% ethyl acetate coagulation bath, 20-30 wt.% flame retardant glass fiber, 0.2-0.5 wt.% dispersant, 0.5-1 wt.% graphene oxide (GO)/dimethylformamide spinning agent and 20-35 wt.% graphene oxide short fiber. USE - Used as graphene fiber flame-retardant conductive non-woven fabric. ADVANTAGE - The fabric has specific conductance and thermal conductivity. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for preparing the non-woven fabric, comprising (i) injecting graphene oxide (GO)/dimethylformamide spinning dope into a 40-50 rotation ethyl acetate coagulation bath to continuously spin the Go short fibers, (ii) subjecting the rotary coagulation bath excessively stretches the extruded fiber by friction to form a GO short fiber having a specific length, (iii) adjusting the speed ratio of the injected Go/dimethylformamide spinning dope to the rotation, the length of the Go short fiber can be easily controlled, and fixing the Go short fiber increases with the increase of the speed ratio until a continuous fiber is obtained when the position of the spinning nozzle, continuous short fibers of Go length are obtained continuously, (iv) collecting and adding flame-retardant glass fiber by filtration and drying at 60 degrees C or lower, and redispersing in a mixture of water and ethanol to form a temporarily uniform GO fiber pulp, (v) drying the spun GO fiber pulp, and drying to become a brown GO, a separate GO fiber fabric, (vi) subsequent filtration and drying allow the Go fiber fabric to be mixed into the graphene conductive paste and further converted into graphene fiber non-woven by thermal annealing at 1000 degrees C, 2000 degrees C and 3000 degrees C, and (vii) subjecting the formed graphene fiber nonwoven fabric to a hot press nip rolling treatment, and finally, providing the graphene fiber flame-retardant conductive nonwoven fabric wound into a roll by a winder.
