英文摘要 | The effect of curing process on the low temperature relaxation behavior of catalyst-cured epoxy systems, which are based on diglycidyl ether of bisphenol A (DGEBA) has been characterized by thermally stimulated discharge current(TSDC) technique. In these chemically relatively simple epoxy systems, three relaxation peaks, designated as γ, ß and ß', have been observed, and their molecular origins are discussed. These observations suggest an inhomogeneous crosslink density morphology which relates the curing process to the nodular structure. |
