In order to decrease the pollution to sea water during the course of oil and water replacement, oil and water separating membrane will be adopted. Considering the expansion and contraction of oil and water separating membrane, transmission of wave pressure and the density difference between the oil and water, the membrane may be damaged by tension, buckling, friction, scraping and so on. Thus, the material used as oil and water separating membrane should have enough strength and flexibility. The generally used coating fabrics were discussed in this paper as per the coating agents, base cloths, and coating methods. Glass fiber cloth coated with silica gel and polyurethane coated fabrics were chosen and a series of tests were performed as per the corresponding standards. By analyzing the test results, the preferred material for oil and water separating membrane was proposed.
