A novel solution-stamping process for preparation of a highly conductive aluminum thin film.

A novel solution-stamping process for the preparation of a highly conductive aluminum thin film on both rigid and flexible substrates is proposed. The superior electrical properties of Al thin films fabricated by the solution-stamping process compared to silver and gold films fabricated from colloidal nanoparticles are experimentally demonstrated, and their applications in electronic circuits on rigid and flexible substrates and to organic light-emitting diodes (OLEDs) are investigated.
