Effects of functionalization on thermal properties of single-wall and multi-wall carbon nanotube-polymer nanocomposites.
Carboxylic functionalization (-COOH groups) of carbon nanotubes is known to improve their dispersion properties and increase the electrical conductivity of carbon-nanotube-polymer nanocomposites. We have studied experimentally the effects of this type of functionalization on the thermal conductivity of the nanocomposites. It was found that while even small quantities of carbon nanotubes (~1 wt ...
متن کاملAb Initio Study of Chirality Effects Onphonon Spectra, Mechanical and Thermal Properties of Nearly Samediameter Single Wall Carbon Nanotubes
In this paper, we have used density functional perturbation theory (DFPT) and Pseudo-potential method to calculate the phonon spectrum, phonon density of states (DOS), specific heat capacity and mechanical properties of (5,5) armchair and (9,0) zigzag Single Wall Carbon Nanotubes (SWCNTs). Our calculations show that Young’s modulusfor (5,5) and (9,0) nanotubesare higher than 1TPa. We have also ...
متن کاملFunctionalization of Carboxylated Multi-wall Nanotubes with 1,2-phenylenediamine
In this paper, the chemical functionalization of carboxylated multi-walled carbon nanotubes (MWNT-COOH) by 1,2-phenylenediamine, have been investigated. MWNT-benzimidazole is obtained through MWNT-Amide reaction with POCl3 after 72h, which is confirmed by FT-IR, SEM, TGA, and elemental analysis. These functionalizations have been chosen due to NH2 and NHCO active sites in MWNT-Amide for future...

متن کاملThermal Conductivity of Single-Wall Carbon Nanotubes
Despite the significant amount of research on single-wall carbon nanotubes, their thermal conductivity has not been well established. To date only one experimental thermal conductivity measurement has been reported for these molecules around room temperature, with large uncertainty in the thermal conductivity values. Existing theoretical predictions based on molecular dynamics simulation range ...
