Large-Displacement Indentation Testing of Vertically Aligned Carbon Nanotube Arrays
Mechanical properties and deformation of the vertically aligned carbon nanotube arrays (VA-CNTs) has been examined with large-displacement indentation tests inside a scanning electronic microscope (SEM). The in-situ indentation allows for establishment of the load-depth responses and real-time observations of the deformation processes. Under a cylindrical, flat indenter, the VA-CNTs exhibit ela...
متن کاملControllable viscoelastic behavior of vertically aligned carbon nanotube arrays
We have characterized the mechanical behavior of aligned carbon nanotube (CNT) arrays that serve as foam-like energy absorbing materials, by using atomic force microscope indentation. It is shown that the mechanical properties (e.g. elastic modulus, adhesion force, and energy dissipation) of aligned CNT arrays are dependent on the length of CNTs as well as chemical environment that surrounds CN...
متن کاملHeight independent compressive modulus of vertically aligned carbon nanotube arrays.
The compressive modulus of dense vertically aligned multiwalled carbon nanotube (CNT) arrays synthesized by chemical vapor deposition was investigated using an optically probed precision-loading platform. For CNT arrays with heights ranging from 15 to 500 microm, the moduli were measured to be about 0.25 MPa and were found to be independent of array height. A continuum mechanics model based on ...
متن کاملSurface properties of vertically aligned carbon nanotube arrays
This study focuses on the structural changes of vertically aligned carbon nanotube (CNT) arrays while measuring their adhesive properties and wetting behaviour. CNT forests grown by chemical vapor deposition with a height of ~100 μm, an outer CNT diameter of ~10 nm and a density of the order of ~10 CNTs/cm show an average adhesion of 4 N/cm when pressed against a glass surface. The applied forc...
متن کاملOptical characterization of vertically aligned single-walled carbon nanotube arrays
Here we discuss spectroscopic investigation and characterization of vertically aligned single-walled carbon nanotube (VA-SWNT) arrays, which were synthesized using the alcohol catalytic CVD method [1]. Growth of the VA-SWNTs was monitored using an in situ absorbance measurement [2], which provides information about the growth process. Primary methods employed were Resonance Raman and UV-Vis-NIR...
