Copolymer segregation behaviour has been studied using the technique of neutron critical reflection from layered samples. Surface segregation occurs due to location at the air/polymer interface of a copolymer microphase-segregated layer. Similar microphase segregation by the copolymer occurs during mutual diffusion with the homopolymer. By comparison with theoretical predictions, this segregation is shown to exhibit behaviour characteristic of end-tethered polymer brushes.
