Claim Text:
1. A method of preparing a hydrophobic or superhydrophobic woven fabric surface having hybrid pores comprising: preparing micro-nano hybrid pore structure by forming nano sized pores on the surface of the woven fabric having micro sized pores by plasma etching; and forming hydrophobic film on the micro-nano hybrid pore structure prepared in the preparing micro-nano hybrid pore structure, wherein the hydrophobic film is amorphous carbon thin film containing silicon and oxygen (a-C:H:Si:O) formed through plasma-enhanced chemical vapor deposition (PECVD) method, and the forming hydrophobic film is carried out using a gas mixture comprising hexamethyldisiloxane (HMDSO) and oxygen with an oxygen fraction of 10 to 30%.
