This study included the preparation of cyclic maleimides by the process of water withdrawal using water-extracting agents and ring-closing of amino acids prepared by a previous step of reacting aromatic amines containing two amino groups with maleic anhydride. The synthesized organic compounds were evaluated using melting point analysis, infrared (IR) spectroscopy, proton nuclear magnetic resonance (1H NMR), and carbon nuclear magnetic resonance (13C NMR). Inexpensive graphene nanosheets of partly reduced graphene oxide (p.rGO) were synthesized using the ball milling of coal, which was dampened with deionized water droplets. They were used to prepare five nanocomposites by chemical sublimation with the prepared cyclic maleimides in the presence of deionized water. The prepared nanocomposites were characterized by spectroscopic methods.
