AC Impedance Spectroscopy Studies on Organic Plastic Crystals

摘要

Electrochemical Impedance Spectroscopy studies were conducted on two organic thermal energy storage materials; Neopentylglycol (NPG) and 2-Amino-2-Methyl-1,3-Propanediol (AMPL). The ionic conductivities and dielectric relaxation times in the low temperature ordered α-phase (monoclinic for both NPG and AMPL) as well as high temperature orientationally disordered cubic γ-phase are reported.
