Abstract :

Transparent flexible electronics are highly demanded for modern technology applications such as solar cells, lightning displays, and wearable requirements. Here porous-nickel-film based flexible and transparent electrodes (FTEs) were investigated. The continuous, holey, and lacey nickel films were fabricated on various polyimide substrates using DC sputtering. The electrical resistance and resistance ratio (R/R0) of the prepared nickel electrodes were characterized under various experimental conditions, such as bending, stretching, and twisting. It was found that the electrical resistance increases in either quadratic (second order polynomial) or exponential trend in the three types of electrodes under bending. During stretching, the resistance increases polynomially, exponentially or linearly with strain rate. The same electrical behavior was observed under twisting. Their physical properties were also characterized with X-ray diffraction, scanning electron microscopy, transmission electron microscopy, atomic force microscopy, and vibrating-sample magnetometer. These fabricated nickel films are magnetic and can be used for several FTE applications in the future.
