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).
