A master’s thesis was discussed in the Physics Department at the College of Education at Al-Qadisiyah University. It was presented by researcher Atyaf Fahim Abdul Abbas and supervised by Assistant Professor Dr. Hanaa Hussein Salman.

The thesis aimed to prepare epoxy nanocomposites supported by nanographene, nanoclay, and nanoaluminum oxide with different layer distributions (binary, ternary, graded, and non-grade). The thesis also aimed to study and evaluate the mechanical and thermal properties of these composites (tensile, impact, flexural, hardness, and thermal conductivity). It also analyzed the chemical and structural interactions between the polymer matrix and the nanoparticles using FTIR technology to clarify the mechanism of performance improvement.

The most important Conclusions: The addition of nanoparticles (graphene, clay, and aluminum oxide) to epoxy improved the mechanical and thermal properties compared to pure epoxy. The graded ternary systems showed the best performance due to the balanced particle distribution and reduced agglomeration.
