Super-hydrophobic surface, with a water contact angle greater than 150o, has a self cleaning effect termed ‘lotus
effect\'. We introduced super-hydrophobicity onto aramid/rayon mixture fabric with dual-scale structure by assembling silica nano-sol.
Mixture fabric was treated with silica nano-sol, fluoric polymer using various parameters such as particle size, concentration. Silica
nano-sol size were measured using particle size analyzer. Morphological changes by particle size were observed using field emission
scanning electron microscopy(FE-SEM), contact angle measurement equipment. The contact angle of water was about 134.0o, 137.0o,
143.0o, 139.5o and 139.0o for mixture fabric coated with 100.2nm, 313.7nm, 558.2nm, 628.5nm and 965.4nm silica nano-sol,
compared with about 120.0o for mixture fabric coated with fluoric polymer. When we mixed particle sizes of 100.2nm and 558.2nm
by 7:3 volume ratio, the contact angle of water was about 146.2o. And we mixed particle sizes of 313.7nm and 558.2nm by 7:3
volume ratio, the contact angle of water was about 141.8o. Also we mixed particle sizes of 558.2nm and 965.4nm by 7:3 volume
ratio, the best super-hydrophobicity was obtained. In this paper, we fabricated the water-repellent surfaces with various surface
structures by using four types of silica nano-sol, and we found that the dual-scale structure was very important for the
super-hydrophobicity.
