Abstract/Description
A series of single-ion, conductive polymers were prepared using thiol-ene photochemistry. The nature of the ion was varied and the thermal and mechanical properties of the resulting polymers were evaluated. As the performance of many of these single-ion conductors are heavily influenced by the presence of moisture (humidity), ionic conductivities were measured as a function of humidity (0, 30, 50 and 70%) and the results were correlated with structural modifications. We found the polymer containing the chloride ion had the greatest response to humidity with a nearly 6-orders of magnitude increase in conductivity from anhydrous conditions to 70% relative humidity.
