-Using Monte Carlo simulations,​ we have investigated the possibility of an orientational melting transition within a "​rope"​ of CNTs. hen twisting nanotubes bundle up during the synthesis, orientational dislocations or twistons arise from the competition between the anisotropic interbute interactions,​ which tend to align neighboring tubes, and the torsion rigidity that tends to keep individual tubes straight. We mapped the energetics of a rope containing twistons onto a alttice gas model and found that the onset of a free "​diffusion"​ of twistons, conrresponding to orientational melting, occurs at //​T//<​sub>​OM</​sub> ​160 K. +Using Monte Carlo simulations,​ we have investigated the possibility of
