Viscoelastic Creep of Vertically Aligned Carbon Nanotubes

Abstract

The paper reports the viscous creep occurring in vertically aligned carbon nanotubes (VA-CNTs). Nanoindentation experiments are conducted to characterize the creep behaviour of the nanotube materials. By recording the instantaneous control stress and strain rate, the creep strain rate sensitivity of the VA-CNT array is calculated. The creep property is found to depend upon the density of nanotube arrays.
