Computer Simulations of Adsorbed Polymer Chains[PACS numbers: 07.05.Tp, 61.25.Hq, 83.10.Nn]

Abstract

The simple cubic lattice model of polymer chains was used to study the properties of adsorbed macromolecules with different internal architectures: linear chains and star-branched chains with 3 arms of equal lengths. The polymer chains were modeled with the excluded volume interactions only, i.e. in good solvent conditions. The chains were placed on an impenetrable surface and a contact potential between polymer segments and this surface was assumed. The strength of this potential was chosen to emulate the conditions of a weak adsorption regime. The Metropolis-like sampling Monte Carlo algorithm was used to determine the properties of the adsorbed polymer film. The size and the internal structure of adsorbed chains were described. The size, distribution and lifetimes of structural elements such as tails, loops and trains were also determined. The differences between the structure of films consisting of star-branched and linear chains were described and discussed. (author)
