  • What percentage of MWCNTs are functionalized with PEG?
  • TGA showed that almost 16% (by weight) of the MWCNTs were functionalized with PEG and 39% (by weight) were functionalized with ODA. The percent surface coverage was estimated for both MWCNTs–ODA and MWCNTs–PEG, and calculations showed that total surface areas covered were 46.3% and 0.38%, respectively.
  • What is side-walled functionalization of MWCNTs?
  • Conclusions Side-walled functionalization of MWCNTs was achieved using polyethylene glycol and octadecylamine. Different characterization techniques were used to investigate the formation of MWCNTs–PEG and MWCNTs–ODA. TGA showed that almost 16% (by weight) of the MWCNTs were functionalized with PEG and 39% (by weight) were functionalized with ODA.
  • Do functional groups exist on the MWCNT surface?
  • The characterization techniques proved the presence of the functional groups on the MWCNT surface. Thermal gravimetric analysis revealed that nearly 16% (by weight) of the MWCNTs were functionalized with PEG and 39% (by weight) was functionalized with ODA. 1. Introduction
  • What characterization techniques are used for oxidized MWCNTs?
  • Different characterization techniques such as FTIR spectrometry, thermogravimetric analysis (TGA), scanning electron microscopy (SEM), X-ray diffraction (XRD), and solubility in different solvents were performed for the oxidized MWCNTs, MWCNTs–PEG and MWCNTs–ODA.
  • What XRD is used for characterization of modified MWCNTs?
  • SEM (Scanning electron microscopy), was used for the characterization of the modified MWCNTs using a JEOL JSM-6400 Digital Scanning Electron Microscope. The XRD (X-ray diffraction) profile was acquired using a Philips automated powder diffractometer (model PW 1710) and nickel-filtered Cu Kα radiation (λ = 1.542 Å).
  • What is the difference between Oda and MWCNT?
  • It is clear from the graph that pure ODA weight decreased sharply with raising the temperature, above its boiling point (55–57 °C) and reached 98% weight loss near 300 °C, whereas MWCNTs–ODA weight decreased steadily with increasing temperature and its weight loss reached 39% at 800 °C.
