Scanning Electron Microscopy Interpretation In Carbon Nanotubes Composite Materials After Postbuckling - Review Paper

Abstract

—Current review paper summarizes the review

on scanning probe microscopy investigations of the

properties and manipulation of carbon nanotubes, and

moreover, the fabrication and utilization of nanotubes as

novel tips for probe microscopy experiments. For small

aspect ratio nanotubes, the boundary constraints begin

to play a major role in the post-buckling behavior and

collapse need not be as catastrophic as in the longer

structure. It is shown that the post-buckling deflection

causes driving force mainly in the in-plane and out-of

plane shear modes and the bending mode about the wall

length direction. Depending on the nature and

magnitude of the interfacial toughness, the nano-wall

may undergo no cracking, snap-back fracture and snap

through fracture
