چکیده انگلیسی
A series of epoxy cured samples, with different molar composition of 1,4-butanediol diglycidyl ether (EP), cis-1,2-cyclohexanedicarboxylic anhydride (CH) and triethylamine (TEA) as initiator, was studied by Electrical Impedance Spectroscopy (EIS) in the frequency range 10−2–105 Hz. The resistivity of the system was evaluated by using the complex impedance analysis method. Resistivity values in the range between 107 and 1013 Ω cm were obtained and related to the composition (molar fraction xEP or xCH) of the epoxy system. The gel formation characteristics of the samples were obtained as theoretically described by Flory.
