Development of Nanodevices, Nanostructures, Nanocomposites, and Hierarchical Nanocomposites at Hawaii Nanotechnology Laboratory

摘要

Development of nanodevices, nanostructures, nanocomposites, and hierarchical nanocomposites at the Hawaii Nanotechnology Laboratory of the Department of Mechanical Engineering of the University of Hawaii at Manoa is explained here. On nanodevices, a multifunctional nanobrush using carbon nanotubes is discussed. On nanostructures, a high-performance nanofoam using carbon nanotubes is explained. On nanocomposites, developments on toughening of polymeric materials employing nanoparticles and carbon nanotubes are reported. On hierarchical nanocomposites, first, mechanical properties improvements for continuous fiber ceramic composites using nanoparticles are discussed. Finally, the multifunctional properties improvement of a novel three-dimensional hierarchical nanocomposite employing carbon nanotubes is explained. In closing, the effects of chirality of single-walled nanotubes on their thermomechanical properties evaluated analytically using asymptotic homogenization method and numerically employing finite element method are discussed, and analytical closed form solutions for matrix filled nanotube nanocomposites, also verified numerically, assuming generally cylindrical orthotropic properties will be reported.
