The procedure allowing single‐step formation of microscaled thermostable polymer honeycomb patterns is reported. Polymer substrates soluble in chlorinated solvents were pulled from the solvents before their final dissolution and placed into a humid atmosphere. Honeycomb patterns were deposited by this method on polyetherimide, polysulfone (PSF), and polyethersulfone (PESF) substrates. PSF and PESF substrates demonstrated reversibly switchable wetting under UV irradiation/heating cycles strengthened by the Cassie–Baxter wetting regime. Copyright © 2010 John Wiley & Sons, Ltd.
