Expansão térmica de nanotubos de carbono de duas camadas

摘要: The special properties of carbon nanotubes (CNTs) have inspired researchers in many technological applications. Examples macroscopic products that contain or are made CNTs tennis rackets, baseball bats, bicycle frames, lightweight wind turbine blades and boat hulls. In order to get more knowledge about the behavior these materials, either develop new applications improve actual ones, it is important investigate physical individual diverse situations. this work, using tools molecular dynamics simulations, we present three results for coefficient thermal expansion Double Walled (DWCNTs) (5.5)@(10,10) with without defects. types defects considered here atoms at interstitial sites sp connections between walls (5,5)@(10,10) DWCNT. Our methods are, first, validated by calculation Single CNT (SWCNT) (10,10) comparison result from literature. We show This discussed terms diamond.
