ИСТИНА

It is well-known that the process of microphase segregation occurs in the melts of thermodynamically incompatible block-copolymers resulting in the formation of ordered structures of different morphologies (spherical and cylindrical domains of one phase in another, lamellar structures, gyroid structures, etc.). However, the formation of structured film due to microphase segregation in block-copolymer melts is a complicated task from the viewpoint of technical implementation owing to a number of labor-intensive procedures, such as selection of common solvent for both blocks, selection of regime of removing the solvent and film annealing. To simplify the production of nano- and micro-structured films, an approach based on film formation from preliminary formed macromolecular objects may be proposed. In this research, we study the melts formed by block-copolymer micelles (core-shell particles). We test the melt stability and compare the melt structure with corresponding equilibrium phase diagrams. In addition, our aim is the search of new synthetic strategies, which could provide improvement of polymeric materials technology (polymer films based on block-copolymers), as well as application of the methods of computer simulations for prediction of optimal composition and structure of such films.
