Abstract

original image

Dünne Filme mit cokontinuierlichen Morphologien und charakteristischen Längenskalen bis hinab zu 10 nm wurden durch Phasentrennung eines Polymerblends hergestellt. Der Grad an Nichtmischbarkeit zwischen Polystyrol und Poly(2-vinylpyridin) wurde so eingestellt, dass ungünstige Wechselwirkungen zwischen den beiden Komponenten vermieden werden. Die cokontinuierlich strukturierten Filme dienen als Template für dünne nanoporöse Membranen (siehe Bilder).
