Surface-Induced Self-Assembly of Amphiphilic Block Copolymers Bilayers

Description: The SISAL project will tackle the development of a robust and scalable process to direct the self-assembly of amphiphilic block copolymers into solid-supported symmetric/asymmetric bilayers on various substrates with different shapes and physical-chemistries. The main idea here is to take advantage in a row of both i) the specific interaction(s) occurring between one of the two blocks of the BC with the substrate and ii) the polarity of the solvent to trigger the BC self-assembly at the interface. A particular attention will be paid to this solvent switching step central to the assembly process. The build-up and properties of supported copolymer bilayers will be thoroughly investigated on planar and colloidal substrates using a set of dedicated characterization techniques. In a last part, we will put forward the potential of our approach to develop two specific applications: the design of oil-and-water-repellent coatings and the formulation of BC bilayer coated nanoparticles for the biology.
