LAMELLAR STRUCTURE IN A THIN POLYMER BLEND FILM Autor Geoghegan, M, Jones, R, Payne, R, Sakellariou, P, Clough, A, Penfold, J

Polystyrene-rich phases wet both the air and substrate interfaces and are separated by a polybutadiene-rich phase; these layers are very well defined and the interfaces between them are sharp (down to <20 A ̊). …”
