Relaxation Time Study of Gel Electrolytes During Polymerization by MR Methods

Relaxation Time Study of Gel Electrolytes During Polymerization by MR Methods

Paper in proceedings (conference paper)

In the paper, the properties, particularly relaxation times T1, T2, of gel electrolytes based on the NaClO4 inorganic salt are described. For electrolytes with various concentrations of inorganic salts, relaxation times T1 and T2 were measured at regular intervals during the polymerization, using MR techniques. The reduction of relaxation times during the polymerization, namely T1 from the value 5.5 ms to 1.7 ms and T2 from the value 5.5 ms to 1 ms, indicates a change in the internal structure of the gels and a change in their chemical omposition. 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.
