2 纳米技术.热重量分析法测定单层壁碳纳米管的特性 - 摘要

ISO/TS 11308:2011 provides guidelines for the characterization of SWCNT-containing samples by the use of TGA,performed in an air environment. Guidance is provided on purity assessment of SWCNT samples through a quantitative measure of the non-carbon impurity (i.e. metal catalyst) level within the material.

3 纳米技术.根据细观形状因数确定多层壁碳纳米管的特性 - 摘要

ISO/TS 11888:2011 describes methods for the characterization of mesoscopic shape factors of multiwall carbon nanotubes (MWCNTs). Techniques employed include scanning electron microscopy, transmission electron microscopy, viscometry, and light scattering analysis. ISO/TS 11888:2011 also includes additional terms needed to define the characterization of scattered bending persistence length (SBPL). Two approximation methods are given for the evaluation of SBPL. Well-established concepts and mathematical expressions, analogous to polymer physics, are utilized for the definition of mesoscopic shape factors of MWCNTs.

5 硅基质上薄膜导热性的测量 - 摘要

1.1 A standard procedure for the three-omega method is proposed for measuring the thermal conductivity ofa thin, electrically insulating film, on a substrate having a thermal conductivity significantly greater than thethermal conductivity of the film. This method is applicable to a film on a silicon substrate with the followingcharacteristics:a) the film is electrically insulating;b) the film has a thermal conductivity that is less than one tenth the thermal conductivity of silicon;c) the film is uniform in thickness and the thickness lies in the range 0,25 μm to 1 μm;d) the maximum dimensions of the film are limited by the sizes of the preparation and measurementapparatus;e) the minimum dimensions of the film are limited by the minimum size of the circuit element that can beplaced on the film surface.NOTE A specimen approximately 15 mm by 25 mm is of an appropriate size although specimens as small as10 mm × 10 mm are usable.1.2 The method is directly applicable to films of silicon dioxide on silicon wafer substrates.1.3 The method may be applicable to insulating films on other high-thermal conductivity substrates providedthat the parameters of the substrate material are substituted for the parameters of silicon used in this methodand the associated computer program.1.4 The method is applicable to measurements near room temperature.
