  • Patent number: 9289937
    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.
