I m Amin Pirayesh. I got my Master's degree in chemical engineering from Sahand university of technology. I worked on synthesis and characterization of epoxidized polysulfide/modified graphene nanocomposites. In addition, I am working as a manager of polymer department labs and I have become familiar with nanoparticles for some applications. Also, my research Interest are : 1. Investigation of thermophysical and mechanical properties of nanocomposites 2. Polysulfide Polymers: Synthesis, Blending, Nanocomposites, and Applications 3. Surface modification with various compounds 4. Polymer nanocomposite
