X-ray and neutron scattering studies of complex confined fluids

摘要

We review recent X-ray and neutron scattering studies of the structure and211u001edynamics of confined complex fluids. This includes the study of polymer 211u001econformations and binary fluid phase transitions in porous media using Small 211u001eAngle Neutron scattering, and the use of synchrotrons radiation to study ordering 211u001eand fluctuation phenomena at solid/liquid and liquid/air interfaces. Ordering of 211u001eliquids near a solid surface or in confinement will be discussed, and the study, 211u001evia specular and off-specular X-ray reflectivity, of capillary wave fluctuations 211u001eon liquid polymer films. Finally, we shall discuss the use of high-brilliance 211u001ebeams from X-ray synchrotrons to study via photon correlation spectroscopy the 211u001eslow dynamics of soft condensed matter systems.
