“…In particular, signals of 1st, 2nd, and perhaps additional carbon atoms of ODA in 1 H to 13 C cross polarization spectra of ND-ODA are missing due to interactions of the atoms near the amine end of ODA with the large ND particle. Similarly, the missing signals of carbon atoms nearest to the amide bond have been reported before for ODA covalently linked to carbon nano-onions [26] and multi-walled carbon nanotubes [27].…”

“…of MWCNT-COOH sample is due to C=O stretch mode in carboxylic acid, indicating the COOH group in our pristine MWCNT-COOH sample, and the peak at 1625 cm is probably due to the stretching vibration of the amide carbonyl group (υ(C=O)), indicating the formation of the carboxylate group, which is a strong evidence for the successful covalent functionalization of MWCNT with ODA [39]. The small shoulder at 1557 cm in pristine ODA and n-MWCNT-ODA, respectively [37].…”

“…The small shoulder at 1557 cm in pristine ODA and n-MWCNT-ODA, respectively [37]. The peak at 1085 cm [39], they found that the XRD diffraction peak was strongly influenced by adding ODA to MWCNT with different reaction time. In our experiment, the change was also observed.…”

“…Not only SWCNTs with covalent functionalization, but also with non-covalent functionalization could be dispersed well in solvents, which provided us with a straightforward method to make homogeneous nanotube-based copolymers and polymer composites [38]. Xu et al [39] found that ODA chains grafted with multi-walled carbon nanotubes (MWCNTs) were partially crystalized, and they thought that ODA preferred to react at the tube-ends and the defects on the sidewall of MWCNTs. Although ODA can be used to improve the solubility or dispersability of CNT, the application of CNT modified with ODA in plastic nanocomposites is rarely reported.…”

Polyetherimide (PEI) is a widely applied as engineering plastic in the electronics, aerospace, and automotive industries but the disadvantages of extremely low conductivity, atmospheric moisture absorption, and poor fluidity at high temperature limits its application. Herein, commercial multi-walled carbon nanotubes (MWCNTs) were modified with a long alkyl chain molecule, octadecylamine (ODA), to produce a uniform dispersion in commercial PEI matrices. Both covalent and noncovalent modification of MWCNTs with ODA, were prepared and compared. Modified MWCNTs were incorporated in PEI matrices to fabricate nanocomposite membranes by a simple casting method. Investigating mechanical properties, thermal stability, and conductivity of the polyetherimide (PEI)/MWCNT composites showed a unique combination of properties, such as high electrical conductivity, high mechanical properties, and high thermal stability at a low content of 1.0 wt % loading of ODA modified MWCNTs. Moreover, electrical resistivity decreased around 10 orders of magnitude with only 0.5 wt % of modified MWCNTs.

“…Another small peak located at 1540 cm −1 corresponds to the amorphous phase of the carbon hydrogen in the CNT films [16]. The D-line peak can be attributed to the finite particle size effect and the presence of defects in curved graphite sheets [17]. The G-line peak mainly originates from the presence of tubular structure in the CNTs [18].…”

Carbon nanotube (CNT) films were grown on nickel foil substrates by thermal chemical vapor deposition (CVD) with acetylene and hydrogen as the precursors. The morphology and structure of CNTs depending on the acetylene flow rate were characterized by a scanning electron microscope (SEM), a transmission electron microscope (TEM) and a Raman spectrometer, respectively. The effect of acetylene flow rate on the morphology and structure of CNT films was investigated. By increasing the acetylene flow rate from 10 to 90 sccm (standard cubic centimeter per minute), the yield and the diameter of CNTs increase. Also, the defects and amorphous phase in CNT films increase with increasing acetylene flow rate.
