Solvent‐assisted microcontact molding: A convenient method for fabricating three‐dimensional structures on surfaces of polymers

Solvent‐assisted micro‐contact molding (SAMIM) , a non‐photo‐lithographic technique for fabriation of patterned, quasi‐three‐dimensional structures on surfaces of many different polymers, is described. The basis of the technique–an embossing/molding process in which a solvent softens a polymer–is out lined and many examples are given. The Figure shows a polystyrene structure produced using SAMIM with acetone as the solvent. magnified image
