Electric current during electrophoretic deposition of conjugated polymer: A test with various electrode distances

The transient current during electrophoretic deposition of conjugated polymer is a promising tool for exploring the basic process of the deposition. In this paper, it has been shown that the transit times obtained from various electrode distances give almost identical electrophoretic mobility. The result shown here seems to support our interpretation of the transient current profile during electrophoretic deposition that it reflects the drift motion of colloidal particles in suspension driven by the electric field.
