Studies on plants such as lotus leaf suggested that dual-scale structure could contribute to super-hydrophobicity. We
introduced super-hydrophobicity onto poly(ethylene terephthalate)(PET) fabric with dual-scale structure by assembling TiO2 nano
sol. PET fabric was treated with TiO2 sol, water-repellent agent using various parameters such as particle size, concentration.
Morphological changes by particle size were observed using field emmission scanning electron microscopy(FE-SEM) and AFM
measurement, contact angle measurement equipment. The contact angle of water was about 138.5°, 125.8°, 125.5° and 108.9° for
PET fabric coated with 60.2nm, 120.1nm, 200nm and 410.5nm TiO2 particles, compared with about 111.5° for PET fabric coated
with water repellent. When we mixed particle sizes of 60.2nm and 120.1nm by 7:3 volume ratio, the contact angle of water was
about 132.5°. And we mixed particle sizes of 60.2nm and 200nm by 7:3 volume ratio, the contact angle of water was about
141.8°. Also we mixed particle sizes of 60.2nm and 410.5nm by 7:3 volume ratio, the best super-hydrophobicity was obtained.
In this paper, we fabricated various surface structures to the water-repellent surfaces by using four types of TiO2 nano-particles,
and we found that the nanoscale structure was very important for the super-hydrophobicity. |
