Research Area
Amphiphilic molecules may self-assemble, forming rich variety of structures. For fluid systems, a minor change of the environment may cause radical structural changes. Such soft mesoscale structures are found in many systems, including solutions of classical surfactants, block copolymer solutions and melts, biologic membranes, etc. Structural rearrangements often result in a crucial change of macroscopic properties (volume and elasticity of the sample, its viscosity, selectivity with respect to different solvents and salts, electric conductivity and so on). This can be used in the design of environmentally responsive smart materials whose behavior may be manipulated by external stimuli. The role of such materials is rapidly increasing in various applications. The major problem is to relate the macroscopic behavior of a complex fluid system with its molecular structure and to develop predictive models for engineering applications. We perform experimental studies and develop molecular-thermodynamic models for different types of complex fluids.
