Abstract
Provided are a filter fabrication method and the filter formed thereby. In this method, a three-dimensional graphene polymer complex filter can be easily fabricated. By forming various patterns at a surface of a collector, patterns can be simply formed at a surface of a filter. This provides advantages at control of pressure difference which can be one of the very important factors necessary for designing and fabricating a filter. Since the filter includes graphene particles homogeneously combined to the polymer nanofiber, the filter can represent a superior antibiosis.
Claims19
A method of fabricating a filter, comprising:
- 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 graphene•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.
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.
