Abstract (en)

[origin: WO9947570A1] The present invention relates to a method for producing microstructures, nanostructures, or objects. This method involves providing a rod-coil block copolymer including a rigid-rod block and a flexible-coil block, mixing the rod-coil block copolymer and a selective solvent for one of the blocks which solubilizes that block, and permitting the rod-coil block copolymer to self-assemble into organized mesostructures with a region of the unsolubilized block and a region of the solubilized block. Also disclosed are organized mesostructures produced by such a method. Another aspect of the present invention is to produce the organized mesostructure in the form of a mesoporous solid. Yet another aspect of the present invention is a method of producing an adsorption layer of the rod-coil block copolymer and an optical article formed with such an adsorption layer. The present invention also relates to encapsulating and solubilizing large molecules, macromolecules, or nanoparticles by adding large molecules, macromolecules, or nanoparticles to the solution of rod-coil block copolymer and solvent.
