Temperature Effect on the Tensile Mechanical Properties of Graphene Nanoribbons

摘要

The tensile mechanical properties of graphene nanoribbons (GNRs) with five types of edges are investigated in the range of 1K to 800K by molecular dynamics simulations.The results show that the Young's modulus of GNRs varies with different edges,and the Zigzag GNRs have larger Young's modulus and tensile strength than other four types of GNRs.We also found that the tensile strength of GNRs obviously reduces as the temperature increase though it shows different trends under uniform variable and stationary temperature conditions.In addition,the tensile strength is closely related to the variable rate of temperature.
