Thin polymer films with cylindrical microdomains of controlled size (see Figure for an AFM image) have been produced from diblock copolymer/homopolymer mixtures. It is demonstrated that not only do the spatial order and orientation of the domains remain unperturbed but also that two distinct sizes of pores can be accessed from the same film.
