Catecholamine: Air/Water Interfacial Formation of Freestanding, Stimuli‐Responsive, Self‐Healing Catecholamine Janus‐Faced Microfilms (Adv. Mater. 45/2014). (December 2014) - Hong, Seonki
Abstract S. N. Gorb, H. Lee, and co‐workers show on page 7581 the first report on an adhesive catecholamine film that is spontaneously formed at the air/water interface only by the catalytic role of oxygen in air, and its unexplored interfacial properties are examined. The film exhibits a multi‐functionality of strong adhesion, self‐healing, and stimuli‐responsive actuation with a Janus‐faced morphology. This unique air–water interfacial reaction might explain the chemical origin of exoskeleton formation in insects.
