Abstract

We discuss a self-avoiding walk model of the adsorption of a copolymer at a plane surface, where the copolymer contains two types of monomers. We concentrate on the case where one type of monomer (A) has a short-range interaction with the surface and the other (B) has no interaction with the surface. We show that the sequence distribution of the comonomers affects the location of the adsorption transition and that for some sequence distributions the adsorption transition occurs at the same place as for the homopolymer poly-A. Moreover, in some circumstances the crossover exponent is identical to that of poly-A.
