The modification of the surface to impart a stimuli-responsive behavior has gained a lot of attentions in various fields. Solvent-Assisted Micromolding (SAMIM) imprints the pattern on a polymer film softened by a suitable solvent with a soft polymeric mold. Many biological materials exhibit excellent wetting properties brought about by their dual-scale roughness and low-surface-energy coating. In this study, we demonstrated that stimuli-responsive polymer brush could be grown on a multilayer film of macroinitiators deposited on top of cellulose acetate replicated from a lotus leaf. The polymer coating shows reversible switching between superhydrophobicity and superhydrophilicity even after 5 cycles of heating and cooling.
