Abstract

Nanometer thin membranes with considerable application potential in micro mechanics and materials science can be prepared by transferring cross-linked monomolecular layers of polyisoprenes or polyisobutenes with ionic head groups from the water surface to solid substrates with holes. Especially if monolayers of low glass transition polymers are cross-linked, elastomeric membranes are obtained, which might find application in micro mechanical devices like membrane valves and pumps. Incorporation of hydrophobised colloids leads to composite membranes, which can be converted into porous membranes via removal of the colloids.
