architecture
based on hydroxy diphenyl sulfone bis para-ester phosphoric triglycidyl ether
(TGEHDSEP) is presented. The viscometric properties of the synthesized resin
using an Ubbelohde type capillary viscometer were investigated and were thermally
crosslinked using the hardener methylene dianiline (MDA). The viscosity values of
the new trifunctional epoxy resin TGEHDSEP increased as the pre-polymer mass
concentrations increased, as expected, and as the sample temperature increased,
the viscosity of the system (TGEHDSEP/ethanol) decreased. A new nanocomposite
composed of the prepared resin, TGEHDSEP, and carbon nanotubes (CNT) was
developed using a variety of formulations to optimize the rheological behavior and
thermal stability of the epoxy matrix. The effect of the CNT filler in admixture with
the TGEHDSEP/MDA system in this series of formulations on the nanocomposites
rheological properties was studied. The rheological and thermal properties of the
formulated materials were assessed using the RHM01-RD Haaks rheometer and the
thermogravimetric analysis (TGA) in the dynamic regime, respectively. The results
showed that the G′ (storage modulus) and G′′ (loss modulus) of various nanocomposites
increase as the filler CNT content increases. Over the entire frequency range
studied, the storage modulus G′ is much higher than the loss modulus G′′ for methylene–
dianiline crosslinked nanocomposites formulated with varying percentages
of CNT. The storage modulus G′ of all prepared nanocomposites increases as the
percentage of CNTs increases. These results also show that the addition of carbon
nanotubes to the epoxy matrix improves its thermal properties significantly. The
morphology of the prepared nanocomposites, analyzed by scanning electron microscopy
(SEM), varies significantly with the percentage of carbon nanotube filler
