Abstract
Abstract Carbon nanotube (CNT) has been evolved as a novel material in diverse applications since its discovery. Functionalization of multi-walled carbon nanotube (MWCNT) with different functional groups namely carboxylic, amine and polyethylene glycol (PEG) has been the central point of this work. The functionalized MWCNTs were made nanocomposite with manganese ferrite nanoparticles, synthesized through solvothermal method. Formations of crystalline ferrites were confirmed through X-ray diffractograms (XRD), which shows formation of spinel cubic phase. Uniform size distribution of manganese ferrite (MnFe2O4) nanoparticles synthesized by solvothermal method was confirmed by high resolution transmission electron microscope (HRTEM) images. Fourier transformed infra-red spectroscopy (FTIR) was employed to study the vibrational features of the functionalized MWCNT and MWCNT/ MnFe2O4 nanocomposites. Vibrating sample magnetometer (VSM) study shows the ferromagnetic behavior of the MWCNT/MnFe2O4 nanocomposites. Functionalized MWCNT/MnFe2O4 nanocomposites were subjected to hyperthermia studies with minimal concentration (2mg/ml) and magnetic heating efficiency has been studied.
