Polytetrafluoroethylene (PTFE) coated Nickel foam displaying superhydrophobic and superoleophilic properties for oil water separation. |
| 초록 |
Superhydrophobic and superoleophilic Ni foam was constructed by dip coating and drying method. The Ni foam was dipped in a polytetrafluoroethylene (PTFE) rich coating mixture of PTFE dispersed in a poly (vinylidene fluoride) (PVDF) solution also containing fumed silica, R805. The as prepared Ni foam showed superhydrophobic and superoleophilic properties simultaneously and had a contact angle (CA) of 1560 for water and 00 for oil. It maintained high separation efficiency after repeated separations (ten times) above 96 % for the more viscous olive oil/water mixture and above 99 % for the hexane/water mixture. The as-prepared nickel foam proved to be an excellent candidate for the separation of oil and water mixtures. |
