Evaluation the Electrical Conductivity of PEDOT: PSS as a Function of an Electrode Metal Type Under the Impact of a Neodymium Magnet

The Poly (3,4-ethylene dioxythiophene): polystyrene sulfonate (PEDOT:PSS) thin films were coasted after dilution with a distilled water, then applying it on different metal substrates by the casting method. An annular neodymium magnet (with 5 cm in diameter and 70 milli Tesla) was used in this study. All substrates are positioned in the center of a magnet during the coasting prosses. The intrinsic electrical conductivity of this semiconductor polymer is 9×10-4 S.cm-1. We used a range of substrates to cast several thin films onto various copper, aluminum, and ITO electrodes, each substrate dimensions are (2x2) centimeters.
The 25, 50, and 100 milliliters were taken since we used distilled water as a dilution solvent, the findings indicated that 50 milliliters of solvent were the optimal amount to apply to the aluminum electrode. As indicated earlier, one aspect of this effort is the use of many electrodes. Using varying amounts of solvent is the second dimension. The results explain the magnet affact the electrical conductivity of PEDOT:PSS up to 5×10-2 S.cm-1, after which the conductivity only increased by 100 times. The electrical conductivity of PEDOT:PSS is influenced by the type of electrode metal.
