60‐2: Direct Patterning of Fine Electrodes by Wettability Control of a Novel Photocrosslinkable Polymer Insulator for Solution‐based OTFTs

A novel, photocrosslinkable styrene‐based polymer was developed for use in organic thin‐film‐transistors (OTFTs). This polymer exhibited high electrical insulation and a low dielectric constant. Upon exposure to parallel vacuum ultraviolet irradiation the polymer became hydrophilic, which created patterned regions that formation of Ag electrodes from aqueous solution. Solution‐processed short‐channel OTFTs with printed silver electrodes were fabricated and investigated.
