The invention provides a high-precision and interval-controllable
electrode and a preparing method of high-precision and interval-controllable electrodes. The method comprises the steps that firstly, a substrate is designed and prepared, wherein
high surface energy regions and lower
surface energy regions are alternately arranged on the substrate; the
high surface energy regions are fully paved with a solution or
emulsion including conductive fillers; then,
evaporation diffusion is conducted, along with the volatilization of the
solvent, the freely-diffused conductive fillers are gathered and arranged on the boundary regions, adjacent to the low
surface energy regions, of the
high surface energy regions, the lower
surface energy regions serve as dams and are used for controlling the further
diffusion of liquid drops, the diffused and arranged conductive fillers are solidified through heating or
photon sintering and then form interval-controllable high-precision electrodes, and the intervals of the electrodes are controlled by the width of the high surface energy regions. The high-precision and interval-controllable
electrode prepared through the method has important application on the aspect of preparing high-precision electrodes of devices such as transparent conductive films, high-end sensors, transistors, storage devices and capacitors.
