    摘要: A liquid resin composition prepared by mixing an ionic material and/or a chargeable material into a thermosetting or thermoplastic resin is injected into a mold having a predetermined inner shape, and a DC voltage is applied to the liquid resin composition to concentrate the ionic material and/or chargeable material on a desired portion or to distribute the ionic material and/or chargeable material continuously. Thereafter, the resin composition is thermally cured when the resin composition contains the thermosetting resin, or the resin composition is hardened by cooling when the resin composition contains the thermoplastic resin, thereby obtaining a molding having a predetermined shape.
