| 제목 | Superhydrophobic and superoleophilic Nickel foam by a simple dip-coating method using a mixture of polytetrafluoroethylene, fumed silica and poly(vinylidene fluoride) as binder 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 mixture containing polytetrafluoroethylene (PTFE) and hydrophobic fumed silica (R805). The mixture was dispersed in a poly(vinylidene fluoride) (PVDF) solution. The PVDF was used as a binder. The as prepared Ni foam showed superhydrophobic and superoleophilic properties simultaneously and had a water contact angle (WCA) of 155° for water and an oil contact angle (OCA) of 0° for oil. The PTFE-coated Ni foam 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.
