Surface morphology of drying latex films: multiple ring formation

Summary

The experiment was simple: a small drop of a monodisperse solution of particles (either 0.008% (w/w) solution of 0.88 um diameter particles, or 0.01% solution of 3.15 um particles) was placed on a glass microscope slide. The drying process was then captured on camera. As the solution evaporated it formed concentric rings of particle arrays.

Rings formed by the evaporation of a solution containing 0.88 um particles. The drop volume is written below each image, while the ring diameter is written above.
