Abstract:
Production of an electrically conductive surface layer on moulded articles consisting of plastics which are soluble or can be swelled in organic solvents, the conductivity of which surface layer is based on a system embedded therein of… - organic electron acceptors (I) on the one hand and… - organic electron donors (II), iodides (III) or mixtures of (II) and (III) as electron donors on the other hand,… in that the moulded articles are treated with organic solutions of these components. … The products of the process have a surface resistance between 10 and 10 ohms and have the advantage that the other characteristics of the moulded articles are virtually uninfluenced by the means (I) to (III).
