Method for dispersing conductive particles, and electrostatic adsorption device

A method for preparing dispersed conductive particles, the method comprising:

• disposing blend particles on a disposition part of a first electrode of an electrostatic adsorption device, wherein each of the blend particles comprises a plurality of the conductive particles attached to an intermediate particle that is larger in size than the conductive particles;
• forming an electric field between the first electrode and a second electrode of the electrostatic adsorption device, the second electrode including an adsorption part facing the disposition part of the first electrode, wherein the adsorption and disposition parts each have electrostatic diffusivity or conductivity,
• wherein the electric field causes the blend particles to reciprocate between the disposition part and the adsorption part of the electrostatic adsorption device, thereby causing the conductive particles to detach from the intermediate particle and be dispersedly adsorbed onto the adsorption part;
• providing an additional electrostatic adsorption device including a third electrode including an additional adsorption part;
• disposing the second electrode including the adsorption part on which the conductive particles dispersedly adsorbed so that the adsorption part faces the additional adsorption part;
• and
• forming an additional electric field between the second electrode and the third electrode of the additional adsorption device,
• wherein the additional adsorption part has an insulating property, and
• wherein the additional electrical field causes the conductive particles dispersedly adsorbed onto the adsorption part to be electrostatically adsorbed onto the additional adsorption part.
