Dynamic images of a droplet impacting on different-layered mask

Caption

The droplet impacting on the mask surface is recorded at 20,000 frames per second. These time sequence images of droplet impingement on a single-, double-, and triple-layer masks show the total number count of atomized droplets is significantly higher for the single-layer mask in comparison with the double-layer mask, while only a single droplet penetrates through the triple-layer mask.
