  • Title: Direct UV-replica molding of biomimetic hierarchical structure for selective wetting.
    Author: Choi SJ, Suh KY, Lee HH.
    Journal: J Am Chem Soc; 2008 May 21; 130(20):6312-3. PubMed ID: 18439007.
    Abstract:
    describe a one-step UV-replica molding method for fabricating a biomimetic dual-scale hierarchical structure. The use of UV-curable, acrylate-functionalized perfluoropolyethers allows for a high fidelity replication of a low-energy surface with multiscale texture, thereby directly creating a superhydrophobic surface without any complicated processing. The superhydrophobic surface can simply be transformed selectively into a superhydrophilic surface by exposure to deep ultraviolet light. The prepared surface is inert to chemicals and solvents and maintains its wettability over a long period of time.
