홈페이지논문 초록 (Abstract)
This study demonstrates a continuous high-resolution roll-to-roll (R2R) microcontact printing (μCP) process capable of printing inks on substrates with a wide range of surface energies. This process is based on rapid solidification of the fluoropolymer ink made up of a low boiling point solvent. The use of a hydrophobic siloxane polymer for the stamp allows film formation onto various substrates due to weak adhesion with the fluorinated polymer ink. To investigate its practical applicability the patterned layer printed by the R2R μCP was used as an etching resistant layer to pattern metallic and dielectric materials with 10 μm resolution. Moreover, the organic and oxide thin-film transistors with the patterned channels were combined to produce the hybrid complementary inverter circuits, having full swing transfer characteristics.
