Abstract
A composition which provides an electrically conductive product upon removal of the water at ambient conditions is described. The composition comprises a dispersed phase of elastomer and a continuous phase of water containing a material selected from the group comprising colloidal silica, alkali metal silicates, and organosilicates. Also present in the continuous phase is greater than 10 parts by weight of electrically conductive particles in the form of fibers having a diameter of less than 25 micrometers and a length of less than 10 millimeters with the ratio of length to diameter of greater than 10:1. Upon drying, the emulsion yields an electrically conductive elastic product having elastomer particles and electrically conductive fibers dispersed in a solid polar continuous phase. The electrically conductive product is particularly useful as an efficient shield for electromagnetic radiation in the radio and television frequencies.
