Ink-jet printing of polymers - from single dots to thin film libraries

Tekin, Emine; de Gans, Berend-Jan; Schubert, Ulrich S.

Abstract:

Recent results on the ink-jet printing of polymer films are presented. Films that were printed using an ink-jet process based on one single solvent always suffered from ring formation, i.e. the coffee-drop effect. This drawback could be overcome by the use of solvent mixtures. The effects of solvent mass ratio, print head velocity, dot spacing and printing method were investigated and optimized to reproducibly obtain homogeneous polymer films (6 x 6 mm size). The results obtained represent an important step towards the application of ink-jet printing for the controlled deposition of polymer dots and libraries.
