Neutron Reflectivity Facility |
|
| The polymers division at NIST utilizes neutron reflection (NR) for probing a wide range of surface and interfacial problems in polymer science. Some recent areas include surface segregation and phase separation in polymer blend films, compatibilization effects of copolymers, interdiffusion kinetics in polymer bilayers, diffusion through membranes, glass transition shifts and thermal expansion measurements of polymer thin films. Such studies result from internal projects of the Polymers Division as well as through external collaborative work with industries and universities, coordinated through the Polymers Division. These studies are conducted in direct collaboration with instrument scientists at the Center for Neutron Research (CNR). Information on instrumental description of the two neutron reflectometers may be obtained at the CNR web-site. | |
