Abstract

The effect of water on dynamics of epoxy-amine networks was investigated using dielectric relaxation spectroscopy (DRS). For DRS measurements in frequency range from 10 ^-2 Hz to 3 MHz, novocontrol α analyzer. It was observed that 2D analysis required external stimuli was equally spaced and DRS spectra were adjusted by linear interpolation. The dielectric loss in frequency domain was found to increase with increasing water content. The results show that 2D analysis exhibited charge migration and γ relaxation change with increasing water content.
