@article{(Open Science Index):https://publications.waset.org/pdf/6712, title = {On the Oil Repellency of Nanotextured Aluminum Surface}, author = {G. Momen and R. Jafari and M. Farzaneh}, country = {}, institution = {}, abstract = {Two different superhydrophobic surfaces were elaborated and their oil repellency behavior was evaluated using several liquid with different surface tension. A silicone rubber/SiO2 nanocomposite coated (A) on aluminum substrate by “spin-coating" and the sample B was an anodized aluminum surface covered by Teflon-like coating. A high static contact angle about ∼162° was measured for two prepared surfaces on which the water droplet rolloff. Scanning electron microscopy (SEM) showed the presence of micro/nanostructures for both sample A and B similar to that of lotus leaf. However the sample A presented significantly different behaviour of wettability against the low surface tension liquid. Sample A has been wetted totally by oil (dodecan) droplet while sample B showed oleophobic behaviour. Oleophobic property of Teflon like coating can be contributed to the presence of CF2 and CF3 functional group which was shown by XPS analysis.}, journal = {International Journal of Materials and Metallurgical Engineering}, volume = {7}, number = {6}, year = {2013}, pages = {463 - 467}, ee = {https://publications.waset.org/pdf/6712}, url = {https://publications.waset.org/vol/78}, bibsource = {https://publications.waset.org/}, issn = {eISSN: 1307-6892}, publisher = {World Academy of Science, Engineering and Technology}, index = {Open Science Index 78, 2013}, }
