Synthesis of Magnetic Carbon Nanotubes (Mag-CNT) by Chemical Vapor Deposition (CVD) Method and Modification for CNT/Epoxy Resin Composite Filler

Abstract

Abstract Magnetic Carbon Nanotubes (Mag-CNT) were synthesized using the chemical vapor deposition (CVD) method with an incoloy® 800 catalyst. The gases used in this synthesis are argon, acetylene, nitrogen, and hydrogen. Mag-CNT purification was carried out by soaking in toluene organic solvent for 12 hours and vacuum annealing at 800°C for 3 hours. Mag-CNT characterization using FTIR, TEM, SEM, Raman, and XRD. Epoxy/Mag-CNT composites were made by modifying the Mag-CNT surface using amino functionalization. Surface modification of Mag-CNT with amino functionalization allows homogeneous distribution of Mag-CNT with epoxy resin. Amino functionalization of Mag-CNT converts hydrophobic nonpolar surface of Mag-CNT to polar and hydrophilic. The addition of Mag-CNT to the epoxy resin will affect the mechanical properties of the composite. Tensile and Hardness tests were carried out to determine changes in the mechanical properties of Mag-CNT/Epoxy Resin composites.
