Abstract in another language

The packing of cylindrical Keggin-Type polyoxometalate hybrid micelles and its influence on specific surface area was studied as function of aspect ratio. Core-crosslinked cylindrical poly(butadiene-block-2-vinylpyidine) (PB-b-P2VP) micelles were used as templates for mesostructuring phosphomolybdic acid (H3PMo12O40). Prior to hybrid formation the length of the cylindrical PB-b-P2VP micelles was adjsuted by sonication. Depending on the aspect ratio of the cylinders a remarkable and unexpected evolution of specific surface areas was observed. The changes in the specific surface area could be explained by a series of scanning electron microscopy and transmission electron microscopy images and were related to the packing of the 1D nanoobjects.
