Means for and method of making paper electrically conductive, wherein the paper is first impregnated throughout with tiny metal particles which have been dispersed in a water-soluble adhesive, after which the impregnated paper is treated with a dilute acid and the exposed metal surfaces displaced by treating with a soluble salt of a more noble metal to provide bridges of noble metal between the metal particles and thus create an electrically conductive path. By applying the metal particles throughout the paper, the resulting product will be completely conductive; but, if the metal particles are applied throughout the paper and then cleaned from the paper surfaces prior to the displacement reaction, the product will have transverse conductivity only. Moreover, if the paper is first presoftened and the treatment applied to one surface thereof, the product will be transversely conductive as well as conductive upon the treated surface. Also, if the treatment is applied to dry paper at reduced temperatures, the product will have only surface conductivity.
