Kinetics And Thermal Properties Of Epoxy Resins Containing The Ionic Liquid [C(6)Mim]Fecl4

The 1-hexyl-3-methylimidazole ferrum tetrachloride salt ([C(6)mim]FeCl4) and mixed amines were blended in different mass ratios with bisphenol-A epoxy resin E-51 to obtain a series of cured products at room temperature. The thermal decomposition of the cured products was studied by thermogravimetric analysis, dynamic mechanical analysis, and in situ Fourier-transform infrared spectroscopy. The thermal degradation temperatures changed as a function of different mass ratios of [C(6)mim]FeCl4. The kinetics of thermal decomposition were then analyzed by the Flynne-Walle-Ozawa method. The results show that the incorporation of [C(6)mim]FeCl4 is a better way to improve the performance of room-temperature curing epoxy resins.
