Glass Fiber Reinforced Epoxy-Amine Thermosets and Solvate IL:
(a) ATR-FTIR spectrum of PEGDE (blue), PEA (red), crosslinking matrix (green), and CGPE-GFA (orange) and CGPE-GFW membranes (purple). (b) Magnified view of the FTIR spectra between 1800 and 400 cm −1.The spectra of PEGDE and PEA showed the characteristic absorption bands at approximately 2868 and 2970 cm −1, attributed to the symmetric and asymmetric stretching
