Abstract:Smart surfaces containing thermo-responsive hydrogels have been investigated for several decades, but the development of mechanically durable and versatile surfaces that can undergo distinct property changes remains a challenging task. Herein, we prepare smart surfaces showing reversible changes in micro-scale roughness, which are attachable to various polymeric substrates. The hydrogel microphase located between silicone phases responsively rise and descend (volcanic-terrain-mimetic transition); as a result, … Show more
