Mild nitric acid treatments to improve multi-walled carbon nanotubes dispersity and solubility in dielectrophoresis mediums: Fullerenes, Nanotubes and Carbon Nanostructures: Vol 0, No 0


The most important limitation of carbon nanotubes (CNTs) is their poor solubility within the frequent solvents. Fixing the solubility concern of CNTs is comprehended both by functionalizing the CNTs or utilizing a dispersity agent. Brokers corresponding to ionic surfactant dramatically alter the suspension conductivity inflicting undesirable thermal move in dielectrophoresis (DEP) mediums. On this research, the dearth of CNTs solubility in frequent solvents was resolved by functionalizing multi-wall carbon nanotubes (MWCNTs) utilizing a light regulated process. The delicate remedy was used to keep up conductivity of MWCNTs, since its important for his or her dielectrophoretic response. Fourier-transform infrared (FTIR) spectroscopy, high-resolution transmission electron microscopy (HRTEM), and Raman spectroscopy have been used to analyze the remedy high quality. The flexibility of various solvents to dissolve MWCNT agglomerates after remedy was analyzed utilizing ultraviolet-visible (UV-Vis) spectroscopy and dynamic mild scattering (DLS) evaluation. The characterization outcomes point out that the handled MWCNTs by the introduced process comprise hydroxylic and carboxylic purposeful teams and confirmed sturdy solubility in water, dimethylformamide (DMF) and acetone. This research supplies a greater resolution to enhance the processability of MWCNTs in frequent solvents with out degrading their electrical conductivity.
