| Abstract: | A set of poly(ethylene oxide)-poly(dimethylsiloxane)-poly(ethylene oxide) triblock copo-lymers having different block lengths in aqueous solution was stulied by small angle X-ray scattering (SAXS) method. It is shown that the amphiphilic triblock copolymers behave as lyotropoic liquid crystals in concentrated water solution. The respective influences of water concentration, block length on the geometrical parmeters of the supermolecular structures are established. The experimental results can be explained by simple geomerical model. |
