Flexible porous materials with superhydrophobicity have a variety of applications such as membranes for water/oil separation due to their high surface are, low density, and recyclability. In this study, commercially available melamine foam was modified to have superhydrophobicity by two steps. The first step of the modification consisted of the immobilization of silver nanoparticles onto the surface of the melamine sponge, which is followed by anchoring of dodecylmercaptan onto them. The modified melamine sponge showed superhydrophobicity with water contact angle of 150o and exhibited excellent oil/water separation capability. Surface morphology and chemical composition of the modified melamine sponge was examined by SEM, XPS, and ATR-FTIR. |
