The separation of water from oil that is collected in oil spill recovery operation is a continuing and necessary requirement during every stage of the effort. In order to separate oil from oil spill, hydrophobic and oleophilic micro-nano technology is new way to do oil skimming. A hydrophobic and oleophilic mesh is one way for oil skimming. In this study, hydrophobic and oleophilic mesh was obtained by plasma polymerized fluorocarbon coating (PPFC) and Ni-Cu electrodeposition on nikel mesh and oil skimmer using a hydrophobic and oleophilic mesh is proposed to collect oil from oil spill on the sea. In order to evaluate the hydrophobic and oleophilic properties of the mesh, nonstructure and micro-nano structure on mesh are fabricated and C.A (contact angle) and oleostatic pressure was measured. The hydrophobic and oleophilic properties of micro-nano structure on mesh is higher than non-structure on mesh. However, oleostatic pressure of meshs is similar.
The oil-water separation system is designed that oleopilic substrate is contact with the back of mesh. It is possible that mesh with high oleostatic pressure and hydrostatic
separates oil from oil spill. In order to evaluate oil-water separation system, rate of collecting oil was measured. Rate of collecting oil using non-structure mesh is higher
than that using micro-nano structure mesh. It is because that adhesion force of micronano structure is major cause of oil flow slowly on surface of mesh.
Through the results, using bare or nano surface of mesh is more efficient than using micro surface of mesh in oil-water separation system and it is expected that higher open area ratio would show better performance of oil-water separation.
