ABSTRACT

This study synthesized and characterized starch-based polyurethane copper nanocomposites (CuNCs) for biodiesel purification, integrating copper nanoparticles (CuNPs) into the PU matrix to enhance adsorption properties. The synthesis involved reacting starch with diisocyanate to form PU, followed by integrating copper nanoparticles (CuNPs) within the PU matrix. Analytical techniques such as FTIR, ¹H NMR and TGA confirmed the successful synthesis polyurethanes. The nanocomposite exhibited excellent thermal stability, mechanical properties, and promising results in removing impurities from biodiesel, presenting a sustainable solution for the renewable energy sector. Keywords: Starch, Polyurethane, Copper Nanocomposites, biodegradable, diisocyanate
