In this article, we tried to induce siloxane to form microtubes through the way of self-assembly on the surface of polyester fabric and make the fabric super-hydrophobic. After the polyester fabric coated by silicon microtubes, the modified fabric obtained super-hydrophobicity due to the same property of silicon microtubes. We used the ethyl trichlorosilane to deposit the siloxaneon the surface of the polyester fabrics in the nitrogen condition by vapor deposition method. The structures and properties of modified polyester fabrics were characterized by scanning electron microscopy (SEM), Energy Dispersive Spectrometer (EDS), Fourier transform infrared spectrum (FTIR), Thermogravimetric analysis (TG) and oil/water separation testing. The results showed the silicon microtubes had been formed and the Si takes a high mass proportion in the sample, proving the siloxane had been successfully grown on the surface further. Oil/water separation experiment and water contact angle measurement proved that the modified fabric had high super-hydrophobicity and it’s important for application in various environment.
