The combination of MWCNT and Fe3O4 has been widely developed for various fields of application, such as anti-radar material. Unfortunately, these combinations lack impedance matching, that caused reflection loss was decreased. ZnO is known to be a material that can improve impedance matching. This research has successfully developed MnFe2O4/MWCNT/ZnO nanocomposite using the sonochemical and sol-gel methods with the iron sand as the main precursor. The result of XRD analysis showed that manganese ferrite (MnFe2O4) and ZnO had cubic inverse spinel and hexagonal wurtzite structures, respectively. The FTIR spectra showed the presence of Fe-O (628 cm-1), Mn-O (430 cm-1), and Zn-O (480 cm-1) vibrations originated from MnFe2O4 and ZnO. The C=C, C=O, and C=H vibrations at wavenumbers of 1540, 1637, 2320, and 2900 cm-1 were observed from the hydroxyl carbon. Such vibrations confirmed the existence of functionalized MWCNT. The EDX data analysis indicated the MnFe2O4, MWCNT, and ZnO presence from the appearance of Mn, Fe, C, Zn, and O elements. Furthermore, the SEM images confirmed that the MnFe2O4/MWCNT/ZnO nanocomposite tended to form spherical and tube particles, representing the shapes of MnFe2O4, ZnO, and MWCNT particles. © 2023 American Institute of Physics Inc..
