Repellix Super-Hydrophobic Ceramic Coating

Two side-by-side cellphone PCB’s are immersed into water. The Repellix coated PCB (right) appears silvery,
as if a force field were pushing the water away. What we are observing is the reflection of light from the air/water meniscus layer surrounding the Repellix coated board.

As the Repellix board is removed, it remains completely dry, in contrast to the uncoated PCB which wets from the immersion.

Different angles show the effect from alternative viewing conditions.
