Two simple techniques are hydrothermal and dip-coating was applied with low temperature and easy to performance. These methods have remarkable advantages and are the optimal choice for developing superhydrophobic materials without consuming energy or requiring high technical equipment. The set of optimal conditions has been found. Reaction temperature of the first layer of TiO2 is 120oC for 3 hours consecutively with solution pH in the range of 4 5, this process needs to be repeated at least three times before coating the second layer with FTDS in immersed temperature is 60oC for 3 hours. TiO2-FDTS@cotton fabric achieved superhydrophobic state with WCA = 152.9o 1 o and shedding angle is 7o . The SEM image shows a crystalline structure growing over on the surface of the fabric. The FTIR and XRD spectra demonstrate the structure of the surface coated with TiO2 and the superhydrophobic functional group. Besides, self-cleaning property was successfully tested, promising outcomes in stay dried when water successfully washed the surface. Additionally, superhydrophobic cotton fabric shows a reliable oil-water effectively, organic solvent-water separation both in surface water and under water.
