Original Abstract

In the article, the measurement and following calculation of relaxation time T2 of gel electrolytes based on the NaClO4 inorganic salt and measurement of diffusion coefficients are described. The measurement is focused on 1H and 23Na nuclei. The value of relaxation time T2 is obtained by approximation of the measured FID (Free Induction Decay) signal with two exponentials using a genetic algorithm. To measure relaxation time T2, the Hahn echo was used. To measure diffusion, the PFG-SE method (Pulsed Field Gradient Spin) was used. The change of relaxation times and diffusion coefficients during polymerization time indicate a change in the internal structure and chemical composition of gel electrolytes based on NaClO4.
