Abstract
In this paper are introduced basic magnetic resonance (MR) methods for measuring the properties of the conductive gel structure during polymerization, particularly relaxation times T 1 , T 2 . Gel electrolytes based on the NaClO 4 inorganic salt was measured. The measurement deals with 23Na nuclei. In our case to measure relaxation time T 2 , the Hahn echo was used. To measure relaxation time T 1 , the IR techniques (Inversion Recovery) was used. The value of relaxation time T 2 is obtained by approximation of spectral lines and the value of relaxation time T 2 is obtained by approximation of spin echo decline signal with two exponentials using a genetic algorithm for both times. The change of relaxation times T 2 and T 1 of 23Na nuclei during polymerization process indicate a change in the internal structure and chemical composition of gel electrolytes based on NaClO 4 .
