The purpose of this study is to fabricate porous polyurethane (SPU) membranes that maintaining oil absorption performance even in contaminated conditions. To this end, a methylsilicone network was formed on the surface using methyltrichlorosilane followed by the introduction of free hydroxyl groups. The SPU film was prepared by solvent casting method and the SPU membrane was prepared by electrospinning process. The surface topography changes were observed by field emission scanning electron microscopy. The chemical components of the surface changed by the introduction of the methylsilicone network were confirmed by FT-IR, and the wettability of the surface was confirmed to be superhydrophobicity and superoleophilicity. As a result, the self-cleaning effect by superhydrophobicity was induced, and it was succeeded to fabricate the polyurethane membrane which maintained the existing oil absorption performance even in the contaminated state. |
