Conducting Polymer as Transparent Electric Glue

A solvent-free electrically conductive glue using conducting PEDOT:PSS is reported. This electric glue exhibits a conductivity of 102 S cm–1, and can effectively laminate various materials electrically and mechanically. The organic electronic devices fabricated through a lamination process using this electric glue exhibit high performance. The figure shows a laminated polymer light-emitting diode under an electric field.
