Micropatterned ceramics by casting into polymer molds
Patterned ceramic surfaces with a feature resolution in the micrometer range are generated by casting aqueous suspensions of high solids loadings onto nonporous polymer molds. The suspensions are solidified by evaporation of the solvent. High-quality line patterns with an aspect ratio of 1 and a pitch of 3 mum were fabricated for alumina, zirconia, cerium gadolinium oxide, and tin oxide powders using molds of poly(dimethylsiloxane). In addition, alumina parts were also created with molds made of a polyolefin (high-density polyethylene), a fluoropolymer (poly(tetrafluoroethylene-co-hexafluoropropylene)), and an epoxy system.
