Crosslinked Poly(styrene)-block-Poly(2-vinylpyridine) Thin Films as Swellable Templates for Mesostructured Silica and Titania

摘要

Crosslinking of the continuous P2VP component of a poly(d_8-styrene)-block-poly(2-vinylpyridine) block-copolymer film is an effective way to limit mesostructural reorganization during swelling and infiltration of inorganic sol-gel precursor species. In this manner, mesoporous silica and titania films were formed with morphologies that were directly related to those of the pre-formed block-copolymer template films.
