Abstract
We study the conformational behavior of a polymer adsorbed at an attractive nanostring and construct the complete structural phase diagram in dependence of the binding strength and effective thickness of the string. For this purpose, Monte Carlo optimization techniques are employed to identify lowest-energy structures for a coarse-grained hybrid polymer-wire model. Among the representative conformations in the different phases are, for example, compact droplets attached to the string and also nanotube-like monolayer films wrapping the string in a very ordered way. We here systematically analyze low-energy shapes and structural order parameters to elucidate the transitions between the structural phases.
