Electromechanical evolution of Carbon nanotube-coated microfibers
Metadata[+] Show full item record
[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT AUTHOR'S REQUEST.] Carbon nanotubes (CNTs) are best described as seamless cylindrical hollow fibers, comprised of a single sheet of pure graphite with extremely light weight. CNTs have high electrical conductivity, high thermal conductivity and high strength. These properties make CNTs ideal, not only for a wide range of applications but also as a test bed for fundamental science. Since a conventional glass fiber is electrically insulating, CNTs turn glass fibers into multifunctional sensors, moreover, the development of these combination of CNTscoated fibers has started promising opportunities for existing material systems. The Scanning Electron Microscopy was used to obtain the morphology information of CNT coated microfibers. In order to get better understanding the properties of CNT coated microfibers, the nanoindentation-based electrical testing combined an electromechanical instrument method was introduced to obtain the electromechanical properties of CNT coated microfibers. Meanwhile, the numerical simulation was employed to provide a more controlled environment to analyze both CNT forest morphology and the structure-property relationships of CNT forests in applications. Keywords: Carbon nanotubes, CNT coated glass fibers, properties, nanoindentaion, numerical simulation.
