Controlled dispersion of carbon nanospheres through surface functionalization

Synergistic oxidation of NADH on bimetallic CoPt nanoparticles decorated carbon nitride nanotubes

“…By contrast, both D-and G-bands of CNNTs showed blue shifts to a higher wavenumber (11 cm −1 and 5 cm −1 shift respectively) as a result of CoPt NP decoration of the outer surfaces of the CNNTs. Furthermore, the peak intensities of both D-and G-bands were found to be enhanced with respect to that of the D * -band, while the D/G band ratio remained almost constant [29]. Fig.…”

Carbon nanotube functionalized with dodecylamine for the effective dispersion in solvents

“…4b the CNT-AC and CNTAm start their significant weight loss at the temperatures of 430 and 365 • C, respectively. Assuming that the surface modification has a negligible effect on the thermal stability, this behavior can be related to the decomposition of covalent organic groups introduced onto the nanotube surface by the functionalization processes [32]. Furthermore, the residual weights for samples CNT-Ac and CNTAm are 12.4 and 11.6%, which imply that some metal impurities were removed by nanotube surface treatment.…”

Influence of GMA grafted MWNTs on physical and rheological properties of PMMA-based nanocomposites by in situ polymerization

“…In addition, recent studies have developed a 'grafting to' technique, a chemical graft reaction to functionalize the surface of CNTs, in order to enhance the dispersity and compatibility of CNTs. [15][16][17][18] However, conventional chemical fucntionalization of MWNTs through strong acid treatment or their secondary reaction is accompanied by disadvantages such as structural damage and shortening of the CNTs, although the bonding strength is higher than that yielded by physical treatment methods. Thus, a decrease of the aspect ratio of the CNTs could influence the thermal and electrical conductivity and physical properties of the CNT/polymer composites.…”
