Electric-field-induced alignment of electrically neutral disk-like particles: modelling and calculation

Abstract This work reveals a torque from electric field to electrically neutral flakes that are suspended in a higher electrical conductive matrix. The torque tends to rotate the particles toward an orientation with its long axis parallel to the electric current flow. The alignment enables the aniso...
