Neutron reflectivity measurements of homopolymer interfaces reinforced with random copolymers
Abstract
The behavior of random copolymers of polystyrene (PS) and polymethylmethacrylate (PMMA), denoted P(Sf-r-MMA1 - f), at the polymer/air, polymer/polymer and polymer/solid interfaces was investigated by neutron reflectivity. Interfacial broadening shows significant penetration of the copolymer into the adjacent homopolymer.
