Temperature Invariant Rubberlike Viscoelasticity of Carbon Nanotubes from -196°C to 1000°C

摘要

Viscoelasticity describes the ability of a material to possess both elasticity and viscosity, Viscoelastic materials, such as rubbers, possess a limited operational temperature range, (e.g., for silicone rubber: -55 to 300°C) above which the material breaks down and below which the material undergoes a glass transition and hardens. This is because molecular motion that is the origin of viscoelasticity is a thermally activated process [1].
