Abstract

The purpose of this thesis is to compare the conductivities of several solutions now in use in producing electroconductive paper. The testing procedure involved the use of a Kiethyl 610 B electrometer with two aluminum discs for conductance through the sheet and two brass strips for conductance across the sheet. Attempts were made to improve the conductance of the solution by the addition of surface agents in the belief that this would lead to better dispersion and thus to better film continuity. No effective method was found to improve the conductivity of a solution of given concentration. Increasing the concentration from 10% to 30% however did give substantial improvements in conductivity.
