Abstract: Disclosed are a method of uniformly dispersing nickel-plated conductive particles of a single layer within a polymer film by applying a magnetic field to the polymer film and a method of fabricating an anisotropic conductive film using the same. The method of fabricating a film may include forming a liquefied polymer layer by roll-to-roll coating a polymer solution in which a plurality of conductive particles has been mixed, dispersing the plurality of conductive particles included in the liquefied polymer layer by applying a magnetic field to the liquefied polymer layer, and fabricating a solid polymer layer limiting a movement of the plurality of dispersed conductive particles by drying the liquefied polymer layer in which the plurality of conductive particles has been dispersed.
