Abstract
Polymers of single-wall carbon nanotubes - possible new zeolites - are modeled by molecular mechanics (MM2 calculation method). The polymeri zation at issue occurs by bonding of 6 sp(3) atomic pairs in each nano tube unit cell with similar atomic pairs located on 6 neighboring tube s like 2 + 2 cycloaddition in a rhombic two-dimensional C-60 polymer. It is shown these bonding in armchair (n, n) SWNT ropes (n = 6, 8, 10, 12) changes positive radial curvature of tube segments to a negative one. (C) 1998 Elsevier Science B.V. All rights reserved.
