文摘In their tubelike phase,nanowire-adsorbed polymers exhibit strong structural similarities to morphologies known from single-walled carbon(hexagonal)and boron(triangular)nanotubes.Since boron/boron nitride tubes require some disorder for stability the triangular polymer tubes provide a closer analog to the carbon tubes.By means of computer simulations of both two and three dimensional versions of a coarse-grained bead-spring model for the polymers,we investigate their structural properties and make a detailed comparison with structures of carbon nanotubes.
