Abstract
The objective of this work was to synthesize a tetraglycidyl 2,2-bis(4-(4 nitrophenoxy) phenyl)propane epoxy resin (TGBAPPP) from 2,2-bis(4-(4-aminephenoxy) phenyl) propane (BAPPP) and epichlorohydrin. The molecular structure of TGBAPPP epoxy resin was confirmed by FTIR and NMR spectroscopy and its molecular weight was determined by means of epoxy equivalent weight (EEW) titration, gel permeation chromatography (GPC) and ion trap mass spectrometry. The TGBAPPP epoxy resin was further reinforced with organically modified montmorillonite (OMMT) nano clay with varying weight percentages (1–5 wt %) and cured with di-aminodiphenylmethane (DDM). The thermo-mechanical behaviour of TGBAPPP epoxy resin and its nanocomposites was examined by means of dynamic mechanical analysis (DMA). The morphology of the epoxy nanocomposites was investigated by X-ray diffraction (XRD), scanning electron microscopy (SEM) and atomic force microscopy (AFM) studies. The TGBAPPP epoxy resin having optimized nano clay reinforcement showed enhanced thermo-mechanical properties and appears to be an ideal candidate for advanced aerospace applications.
