Wettability of graphene nanoribbon/single-walled carbon nanotube hybrid film

The wettability of a GNR/SWNT hybrid film is modified when the surface part of the SWNT film is unzipped by a Zn/HCl sputtering process.

Synthesis of Nano-MnO2/CNTs Composite and Electrochemical Properties as Electrode Material for Supercapacitor

The manganese oxides (MnO2) with nanostructures was fabricated with non-aqueous alcohol and aqueous solution of potassium permanganate (KMnO4) at room temperature. The test results show that the nano-MnO2 well coated on the surface of carbon nanotube (CNT), while the specific capacitance of the composites with MnO2 deposited on singlewall carbon nanotube (SWNT) was better than coated on multiwalled carbon nanotube (MWNT). The specific capacitance of MnO2 coated on SWNT film can reach 769F/g at scan rate of 5mv/s in the first cycle.

Thermal Conductivity Measurement of Vertically Aligned Single-Walled Carbon Nanotubes Utilizing Temperature Dependence of Raman Scattering

We present a method for measuring the thermal conductivity and the thermal contact resistance between the film and the substrate of vertically-aligned single-walled carbon nanotubes (VA-SWNTs) grown on Si substrate by ACCVD (Alcohol Catalytic Chemical Vapor Deposition) method, utilizing temperature dependence of the Raman spectrum obtained from SWNTs. The method utilizes the excitation laser of the Raman system to heat the VA-SWNT film and measure the temperature simultaneously. The method finds the thermal conductivity of the VA-SWNT film to be around 1 Wm−1K−1 and the thermal contact resistance between the substrate and the film to be around 10−5∼10−6 m2KW−1. The obtained film thermal conductivity is converted into equivalent thermal conductivity of an individual SWNT, whose value is several tens of Wm−1K−1, and is more than an order of magnitude smaller than the reports on individual SWNTs.
