Analogous to the electrical components industry, various concentrations of poly(3,4ethylenedioxythiophene):poly(styrenesulfonate) (PEDOT:PSS) incorporated into cotton fabric may yield the same result for electronic textile applications in which a wide-range of resistances from 0.4 x 10(12) Omega - 5.3 Omega can be obtained without the use of metal, carbon and/or silica nanoparticles and a such differs from most conventional methods. Utilizing the drop casting method for the preparation of conductive cotton fabrics along with the secondary dopant, dimethylsulfoxide (DMSO), (which affects a PEDOT:PSS film's conductivity) a highly electrically conductive cotton fabric with metallic properties can be fabricated for electronic textiles applications. The conductive cotton with 21.7 wt% PEDOT:PSS has a sheet resistance of 1.58 Omega/sq that is approximately 51% lower than the best experimental value reported in the literature for conductive polymer-coated fabrics. Moreover, temperature dependent resistance measurements for PEDOT:PSS-treated cotton reveal that the conductive cotton showed different behaviors, including a metal-semiconductor transition dependent on the PEDOT:PSS concentration. Finally, and most importantly, for the first time we have demonstrated that the conductive cotton fabric with high PEDOT:PSS concentration has the ability to act as a wire in a typical electrical electrode, which could lead to important advances in the replacement of copper by conductive fabric.
