▎ 摘　　要

NOVELTY - Graphene-polymer nanofiber membrane comprises porous membrane in which several pores are formed by cross-linking the polymer contained in the graphene-polymer nanofiber, where the nanofiber has a filamentous network structure in which the filament form of the nanofiber is maintained at 90% or more. USE - The graphene-polymeric nanofiber membrane is useful in sensor, adsorbent, and flow system for detecting cationic dye and removing contaminants (all claimed). ADVANTAGE - The reusable graphene-polymer nanofiber membrane is environmentally-friendly, and is produced in a cost-effective manner, and has an effective removal efficiency of 95% or more with respect to the cationic dye in the aqueous solution. The method is suitable for mass-production of the nanofiber membrane. DETAILED DESCRIPTION - INDEPENDENT CLAIMS are included for the following: (1) method for producing graphene-polymer nanofiber membranes; (2) sensor; (3) adsorbent; and (4) flow system for removing contaminants.
