“…The latter assumption is reasonable because water has a high dielectric constant and has high solubility in polar solvents. The influence of the dielectric constant of the solvent on the solubility of the water molecules is widely described in the literature . Moreover, pertinent to the interface region, the method above is valid when the diffusion of water molecules toward the interface is very low, that is, when a steady state is attained.…”

The conductance of interpenetrated polymer networks (IPNs) containing quaternary amino groups was studied in cyclohexane, toluene, ethyl ether, ethyl acetate, and tetrahydrofurane as a function of water content by electrochemical impedance spectroscopy. IPNs were then used as sensitive materials to detect water traces in organic solvents with promising results for the construction of a moisture sensor. The detection onset for water concentration increased with the dielectric constant of the solvent. Different IPN-based sensors in the same solvent showed a detection limit at lower water concentration if their characteristic plot [conductance/relative humidity (RH%) in air] was shifted toward lower RH%. This suggests that the composition of this class of polymers can be tuned to achieve the best performance for each solvent.
