Electric field (〜5000V/cm) was applied to mesosherules (10μm) containing pitches at 300℃. In the case of a pitch prepared from a Wandoan coal liquid, mesospherules moved to an anode without coalescence. On the other hand, mesospherules transported to a cathode and domein texture was obseved for a pitch from a hydrogenated coal. The lamellae of both the mesospherules aligned parallel to the direction of an electric field.
