Analysis of sulphone based organic–inorganic hybrid epoxy nanocomposites for advanced engineering applications—Study of the mechanical, thermomechanical, XRD, EDS and physical properties

A study was made in the present investigation on sulphone containing tetraglycidyl epoxy nanocomposites to find its suitability for use in high performance applications. The synthesis and characterization of the sulphone tetraglycidyl epoxy resin denoted as ‘B’ was done as reported in our previous study. Nanoclay and POSS-amine nano-reinforcements denoted as N1 and N2 were incorporated into the synthesized epoxy resin. Curing was done with diaminodiphenylmethane (DDM) and bis(3-aminophenyl) phenylphosphine oxide (BAPPO) curing agents denoted as X and Y respectively. In our current research, we continue this research and study the mechanical, thermo-mechanical, X-ray diffraction (XRD), energy dispersive spectroscopy (EDS), viscosity, epoxy equivalent weight (EEW) and gel permeation chromatography (GPC) studies.

► Novel sulphone based tetraglycidyl epoxy nanocomposites were developed for aerospace applications.
► Nano-reinforcements were incorporated and curing was done.
► Excellent results were obtained in the mechanical studies. The nanocomposites developed were flame retardant and hydrophobic.
