Organic thin‐film transistor fabricated between flexible films by thermal lamination

Abstract We propose a novel and complementary method for fabrication of flexible electronics. This method is not based on conventional printing using inks, but is based on the application of a toner‐based method such as Xerox or laser printing, followed by a lamination process. The lamination method is a solvent‐free and material‐saving process that simultaneously seals the devices, and the fabricated flexible devices have structural durability against bending. We have also shown that thermal lamination has an oriented growth effect, and the electrical characteristics of flexible organic field‐effect transistors did not degrade under a bending radius of 1 mm. magnified image In our thermal lamination method, organic thin film transistors are fabricated by a desktop laminator, like making plastic laminated cards.
