SUPERHYDROPHOBIC-SUPEROLEOPHILIC NICKEL FOAMS AND METHOD FOR PREPARING SAME

摘要

The present invention relates to a superhydrophobic-superoleophilic nickel foam coated with a coating mixture comprising polytetrafluoroethylene (PTFE) and hydrophobic fumed silica, as well as a method for preparing the same. The method for preparing a superhydrophobic-superoleophilic nickel foam comprises steps of: preparing slurry; providing a nickel foam to be coated with the slurry; and dip coating the nickel foam with the slurry. According to the present invention, the nickel foam may be coated with a coating mixture comprising polytetrafluoroethylene (PTFE) and hydrophobic fumed silica to prepare a superhydrophobic-superoleophilic nickel foam, thus having an effect of facilitating a separation between water and oil.;COPYRIGHT KIPO 2020
