Abstract
In this article, the properties of gel electrolytes based on the NaClO4 inorganic salt are described. For electrolytes with various concentrations of inorganic salts, relaxation times T 1 and T 2 were measured by means of MR techniques at regular intervals during the polymerization. To measure relaxation time T 1, the inversion recovery (IR) technique was used. The measurement of relaxation time T 2 was performed using the spin–echo (SE) technique. The reduction of relaxation times during the polymerization, namely, T 1 from the value of 5.5 to 1.7 ms and T 2 from the value of 5.5 to 1 ms, indicates a change in the internal structure of the gels and a change in their chemical composition. The waveforms measured will contribute to further studies of gel electrolytes aimed at increasing their electrical conductivity and establishing the influence of water molecules on the conductivity.
