The stability of iodine-doped polyacetylene in aqueous environments and the particular effect of variations in pH upon the stability of the intrinsically conducting polymer has been investigated in a variety of aqueous environments. Stability performance was established by simultaneously monitoring the four-probe electrical conductivity and the steady-state electrode rest potential during exposure of the metallically doped, (CHI{sub 0.18-0.20}){sub x}, polymer over an approximate 10-day period. The normally slow but ever present degradation of iodine-doped polyacetylene which occurs even under inert atmosphere conditions is accelerated in all aqueous environments leading to an often precipitous degradation of electrically based material properties.
