Configuration of an adsorbed polymer molecule: Solvent effect

摘要

The configurational behavior of isolated adsorbed polymer molecules subjected to a solvent effect were simulated by generating selfhyphen;avoiding walks confined to the diamond lattice, excluding firsthyphen;nearesthyphen;neighbor occupancy, in the presence of an interacting solid barrier. The method of exact enumeration was employed. The configurational properties obeyed an asymptotic equation of the form PN agr;Nggr;, wherePrepresents a generalized configurational property, e.g., the average number of segments on the surface, etc., and ggr; is a critical index. Some insight into the mechanism of chain adsorption is advanced from an analysis of the energy dependence of the configurational properties.
