Abstract :
We have attempted to observe straining responses of a multi-walled carbon nanotube (MWCNT) with different growth methods by performing an in situ tensile testing in a scanning electron microscope. Linear deformation and fracture behaviors of MWNT were successfully observed and its force-displacement curve was also measured from the bending stiffness and displacement of the force sensor and manipulator, respectively. We obtained different tensile strength of MWCNTs with different growth methods and the elastic modulus of MWCNTs was also calculated and compared with each other.
