22. This is an interesting phenomenon. The water contact angle on a smooth PMMA surface is below 90°, which demonstrates that PMMA is a hydrophilic material. However, the rough, micelle-de-posited surface turns out to be super-hydrophobic. which is contrary to the prediction of the Wenzel equation, that, by increasing the roughness, the wettability of materials can be enhanced (R. Wenzel, Ind. Eng. Chem. 1936, 28, 988). An X-ray photoelectron spectroscopy measurement of the micelle-deposited surface shows no preferential orientation of PP blocks. Our previous study also demonstrated that increasing the roughness of PMMA increased the contact angle rather than decreasing it [17]. Hence, the super-hydrophobicity was caused by the increase of the roughness of PMMA. We will address this problem in a more-detailed study.
