Quasi-logarithmic spacing law in dewetting patterns from the drying meniscus of a polymer solution

► Gradient striped-patterns were prepared by dewetting at the meniscus region. ► Spacing in the pattern changed almost logarithmically but was slightly deviated. ► An equation was derived to describe the shape of the meniscus. ► A dynamic model is proposed for the stick-slip motion of the drying meniscus. ► The model explains the quasi-logarithmic spacing found in laboratory experiments.
