Fabrication of tetraglycidyl epoxy nano-composites functionalized with amine-terminated zinc oxide with improved mechanical and thermal properties

The aim of the present work focuses on a newly developed ether-linked N, N-tetraglycidyl diamino-diphenyl ether (TGDDE) epoxy resin incorporated with the amine functionalized zinc oxide for the enhancement of the mechanical and thermal properties. TGDDE was synthesized using the starting material of...

TGDDE was synthesized using the starting material of 4,4-diamino-diphenyl ether (DDE) with epichlorohydrin (EPC). The synthesized TGDDE epoxy resin was characterized using FT-IR, 1H NMR and 13C NMR spectral analyses.

The mechanical and thermal behavior of the TGDDE epoxy matrix and nano-composites were analyzed by dynamic mechanical analysis (DMA) and thermogravimetric analysis (TGA). Consequently, X-ray diffraction (XRD), scanning electron microscopy (SEM), transmission electron microscopy (TEM), and atomic force microscopy (AFM) were used for the prediction of the structural and surface morphology of the synthesized epoxy nanocomposites. The mechanical and thermal properties of the synthesized epoxy nanocomposites were enhanced to a greater extent by the inclusion of F -ZnO.
