COPOLYMERS AT INTERFACES - SCALING AND MONTE-CARLO STUDIES

We investigate using scaling arguments and Monte Carlo simulations the adsorption properties of AB-copolymers at the interface between two s elective solvents. For random copolymers adsorption is determined by a single scaling variable, which is the same both for ideal chains and for excluded volume chains; numerical simulations based on the bond fl uctuation model support the scaling prediction very well. For alternat ing AB-copolymers adsorption can be described (through a one-step reno rmalization) as a homopolymer problem at a penetrable interface; scali ng is again obeyed well, as we demonstrate through simulations.
