STUDY OF A MODIFIED MELAMINE SPONGE AND ITS LIPOPHILIC AND HYDROPHOBIC PROPERTIES

In this study, silicone rubber and oil were used to modify melamine sponge obtain lipophilic hydrophobic properties. The result showed that the modification had no effect on intrinsic properties of sponges such as structure elasticity. After modification, changed from hydrophilic superhydrophobic, contact angle could reach 155.7°. addition, also maintained its good oil-absorption performance excellent selective absorption in an oil-water mixture. Using xylene simulate pollutants, rate modified 44 g/g while significant changes after 20 cycles experiments. a reliable stable repeated extrusion cycle above experiments proved method have broad application prospects separation.
