Abstract:We have studied stretchable electrode based on combination of inkjet-printed silver electrode and conductive composite materials for stretchable lighting device applications. Previous stretchable electrodes were mainly realized by either vacuum deposition or inkjet-printing of conductive materials on stretchable substrates. Those stretchable electrodes can well sustain electrical performance at relatively low tensile strain condition (typically under 30% elongation). In order to realize stretchable electrodes that can well sustain electrical performance at higher tensile strain condition (over 30% elongation), conductive composite materials have been also widely used. Recently, CNT-based composite materials have been reported for stretchable electrode applications. However, CNT-based composite has cost issues and it needs a complex fabrication process for having a high conductivity and stretchability. Therefore we combined conductive composite materials with inkjet-printed metal thin film for high conductivity for both low and high elongation conditions. Our approach has advantages of simple patterning capability, high initial conductivity, and compensated low resistance sustaining under tremendously high tensile strain conditions when compared with previously reported methods. Our electrodes showed high conductivity from the inkjet-printed Ag electrode and maintained similar level of conductivity when they are elongated by over 100%.
