A Facile Way to Fabricate Transparent Superhydrophobic Surfaces
A fast, easy, and low-cost way to fabricate transparent superhydrophobic (SHP) surfaces is developed. By simply mixing silica nanoparticles (SiNPs), polydimethylsiloxane (PDMS) and heptane to form a suspension, dip- or drop-coating the suspension onto different surfaces, transparent
SHP surfaces can be obtained. By tuning the ratio of the three components above, transparency of the coating can reach more than 90% transmittance in the visible region, while static water contact angle of the coating can reach as high as 162°. Dynamic contact angle study shows the advancing
contact angle and receding contact angle of water can be as high as 168° and 161°, and the resulting contact angle hysteresis can be as low as 7°. The reported facile way of fabricating transparent superhydrophobic (SHP) surfaces is potential for applications which need both optical
transparency and self-cleaning capability, such as solar cells, optical equipment, and visible microfluidic chips.
