摘要: The dielectric properties of epoxy resin (diglycidylether bisphenol A, DGEBA) with triethylene tetramine (TETA) were investigated by the complex impedance spectroscopy technique. parameters have been measured using parallel plate capacitor method HP 4192A LF Impedance Analyzer in frequency range from 1 MHz to 13 and temperature 25 C 120C. Variations real ( ) imaginary parts constants material studied. general behaviours are found stable increasing up 8 MHz. Over this frequency, an anomaly reported except C. s increase about 9 approximately 10 start rapidly decrease 8.5 they a deep 9.7 increases their smooth above When Cole-Cole plots investigated, below But there appeared rings between -10
