Rheology Laboratory

Equipment located in the Rheological Facility measures the steady state and dynamic response of polymers undergoing shear. The complex rheology of many polymers not only constrains potential applications, but it also limits the way that these materials can be processed. The Rheology Laboratory clusters instruments that measure the mechanical and optical properties of various sorts of polymeric fluids (solutions, gels, melts) as stresses and/or strains are applied. Instruments to characterize these properties for solid polymers are located within the MRSEC Characterization Facility.

To monitor rheo-optical reponse investigators in the laboratory have constructed a special shear cell that fits within a Zeiss optical microscope an arrangement permitting flow birefringence measurements for polymer solutions and conoscopy for flowing liquid crystalline polymers. A second home-built optical instrument makes possible small angle light scattering investigations for various types of polymeric fluids under shear
