Morphological and rheological study of the epoxy polymer and their nanocomposite (NGTHTPTBAE/MDA/TSP) crosslinked by methylene dianiline and formulated by trisodium phosphate

Abstract

The present work consists the elaboration and the rheological behaviors of nanocomposite (NGTHTPTBAE/MDA/TSP) in the presence of the epoxy resin nanoglycidyl trihydrazine 4.4.4-tripropoxy tribisphenol A of ethylene (NGTHTPTBAE), methylene dianiline (MDA) and trisodium phosphate (TSP) used as filler. Furthermore, we have studied the performance of nanocomposites (NGTHTPTBAE/MDA/TSP) crosslinked by methylene dianiline and formulated by trisodium phosphate at different percentages. Then, the storage modulus G' and the loss modulus G'' (or tanδ = G''/G') are established as a function of the temperature. From these dependencies, we determined the glass transition temperature or tanδ maximum. Moreover, tan δ > 1 for liquid-like materials and it becomes lower than unity for solid-like materials. Finally, the dispersion of the trisodium phosphate incorporated into various prepared nanocomposite (NGTHTPTBAE/MDA/TSP) was determined using the scanning electron microscope (SEM).
