This paper reports the method for the preparation and functionalization of the porous and fouling release segmented polyurethane (SPU) membrane that maintaining oil-absorbing performance in fouling conditions. To this end, a methylsilicone network was formed on the SPU film and membrane by introducing free hydroxyl groups followed by the reaction with methyltrichlorosilane. The SPU film and membrane were prepared by the solvent casting and electrospinning method respectively. The topological changes were observed by scanning electron microscope (SEM). The changes in the chemical component and molecular structure induced by the methylsilicone network were confirmed by Fourier-transform infrared spectroscopy (FTIR), and the wettability was investigated by measuring the contact angle for both water and oil droplet. As a result, the self-cleaning effect by superhydrophobicity was observed which make the SPU membrane keep oil-absorbing property after contaminated by particulate fouling. |
