Young’S Moduli

Carbon nanotubes (NTs) have novel electronic properties and exceptionally high Young's moduli on the order of TPa. so NTs have potential applications in advanced composite materials such as conductive polymers, electromagnetic-radio frequency interference (EMI/RFI) shielding material and opto-electronic materials. The utility of the nanotubes in composite applications depends strongly on the ability to disperse the NTs homogeneously throughout the matrix without destroying the integrity of the NTs. Furthermore, interfacial bonding between the NT and matrix is necessary to achieve load transfer across the interface, which is desirable for improving the mechanical properties of polymer composites.In this work, aligned multiwalled carbon nanotubes (MWNTs) produced by continuous chemical vapor deposition (CVD) (see Fig.l), were homogeneously dispersed in polystyrene (PS) matrices by a simple solution-evaporation method. Using this procedure, we made uniform MWNT-PS composite films ∼0.4mm thick for ex-situ mechanical tensile test and very thin films, ∼100nm, for in-situ TEM tests, as shown in Fig.2.

Advanced Applications

Hollow carbon nanospheres (HCNSs), with either carbon nanotube (CNT) or metal oxide nanowire (MONW) decoration on their surface, were synthesised as building materials with a great potential for the next generation advanced applications. A well-established, polymeric latex NS synthesis method and a simply modified version of a microwave (MW) energy-based carbonisation approach, i.e. Poptube, were systematically combined to obtain these HCNSs. Through this simple, facile, affordable and easily scalable ‘combined synthesis method’, it was managed to successfully produce HCNSs with an unique morphological, spectroscopic, thermal and elemental features, all of which were strongly supported by both various material characterisation test results and the relevant previous literature data. Thus, it is believed that the as-synthesised CNT or MONW decorated HCNSs (CNT–MONW/HCNS) from the above-mentioned method would soon become the materials of preference for the next generation advanced applications in various science and engineering fields.

Carbon nanotubes are being seen as a promising new class of electronic materials owing to the change in their properties with chirality and geometry of the nanotube. They are being considered for future VLSI applications due to their superior conductance and inductance properties which are important parameters while considering any material for an interconnect or via applications.In this paper, we report the variation in electrical and thermal conductance as well as inductance of a CNT with its geometrical features using a diameter dependent model. Also the dependence of conductance and inductance of a CNT on the type of nanotubes, tube length and tube diameter has been studied. As we know that at nanometre scale, the electrical and thermal transport properties of the components become extremely important as regards the functioning of the device and it is difficult to accurately measure these properties, therefore predictions using modeling and simulation play an important role in providing a guideline for design and fabrication of CNT interconnects and understanding the working of various other CNT based devices.

AbstractSingle-walled carbon nanotubes (SWNTs) are emerging as an important new class of electronic materials. Both metallic and semiconducting SWNTs have electrical properties that rival or exceed the best metals or semiconductors known. In this article, we review recent transport and scanning probe experiments that investigate the electrical properties of SWNTs.We address the fundamental scattering mechanisms in SWNTs, both in linear response and at high bias.We also discuss the nature and properties of contacts to SWNTs. Finally, we discuss device performance issues and potential applications in electronics and sensing.
