Abstract

We use analytic arguments and molecular dynamics simulations to determine how the chemical sequence distribution affects the conformation of a single AB copolymer at a liquid-liquid interface. We define a parameter f which characterizes this sequence distribution along the chain. We determine L*, the length scale on which the polymer weaves back and forth across the interface. We find that L* as a function of f has a well-defined minimum, and the two limits are analyzed. Molecular dynamics simulations support the conclusions obtained from our analytical results.
