Abstract

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.
