摘要 |
A method of producing an electrically conductive plastic material, the conductive pigment in said material being selected from lamp black, graphite and a mixture of lamp black and graphite wherein the conductive pigment is dispersed in a hydrocarbon solvent, the pigment-hydrocarbon dispersion then being subjected to a vibrational force to cause swelling of the conductive pigment in the solvent and adding a bonding agent having an interface surface tension substantially equal to that of the solvent.
