✦ Synopsis

Under equilibrium conditions the dependence of the electrical conductivity of cotton cellulose (Whatman 42 ashless filter paper) on moisture content was of an exponential type up to 3.5%. The transient conductivity of paper undergoing water sorption has been measured concurrently with the transient moisture content. The transient conductivity was greater than that at steady state, the difference increasing with decreasing initial moisture content. The results are explained in terms of thermal effects due to the heat evolved during water sorption.

A new proton conducting material, poly(vinylidene fluoride) (PVDF) grafted with polystyrene (PS) and sulfonated (PVDF-SPS), has been investigated with regard to water uptake and the state of water in the material. The water uptake was estimated for the materials exposed to liquid water, in the tempe
