▎ 摘　　要

NOVELTY - Fabricating a filter involves: fabricating a graphene-containing solution or a graphene oxide-containing solution; fabricating a graphene-polymer mixed solution by mixing a polymer with the graphene-containing solution or with the graphene oxide-containing solution; fabricating a conducting collector of a three-dimensional shape; forming a three dimensional grapheme-polymer complex filter by electrospinning the mixed solution to a surface of the collector; and separating the three-dimensional graphene-polymer complex filter from the collector. USE - In fabricating graphene-polymer complex filter (claimed) for home appliances such as water purifier, air conditioner and air cleaner; and medical devices in order to filter cell (e.g. leukocyte) of a certain size in blood. ADVANTAGE - The method provides advantages at control of pressure difference which can be one of the very important factors necessary for designing and fabricating a filter; and provides a filter with a superior antibiosis and a three dimensional shape. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for a filter having a bottom surface and a sidewall connected from the bottom surface being composed of a polymer nanofiber and graphene particles or graphene oxide particles combined to the polymer nanofiber.
