The deposition of amphiphilic poly(ethylene oxide)-block-poly(butadiene) (PEO-b-PBD) copolymer micelles is demonstrated on solid substrates. Depending upon surface chemistry, micelle adsorption creates either monolayer or bilayer films. Lateral diffusion measurements reveal that strong coupling between hydrophilic surfaces and PEO blocks creates immobile bilayers, while monolayers retain the fluidity previously observed in vesicular assemblies.

In this article, we review the recent advances in the field of block copolymer membranes. We discuss the similarities and differences between natural membranes and their polymeric counterparts, pointing out the advantages of the latter in applications for biosciences and biomaterials. Membrane properties are discussed in terms of functionality and responsiveness, and the most interesting application possibilities are highlighted.
