Functionalization of Silica Particles towards Cationic Polyelectrolytes using Vinylformamide and 1, 3-Divinylimidazolidin-2-one as Monomers

摘要

The use of vinylformamide and l,3-divinylimidazolidin-2-one, bisvinylethylene-urea (BVU), as well as of the poly(vinylformamide-vinylamine) copolymer (PVFA-co-PVAm) for silica surface functionalization has been investigated. Various procedures such as grafting from, crosslinking surface polymerization, and post-functionalization of adsorbed PVAm chains have been experimentally applied. The advantage of the different synthetic methods is discussed with regard to the resulting surface structure of the organic/inorganic hybrid materials.
