Polymer electronics are one of the most active research areas in material science,information science and energy science,because it can offer new ways to create a new generation of large area,flexible and low cost electronics.For example,a voltage is applied to a polymer,which can emit light such as RGB three primary color for full color PLED(Polymer Light-emitting Diodes),even white light for white PLED.In turn,light is absorbed by a polymer to produce electric current,that Polymer electronics are one of the most active research areas in material science, information science and energy science, because it can offer new ways to create a new generation of large area, flexible and low cost electronics.
