The Physical Chemistry of Multicomponent Polymer Solutions: Complex Nanostructures and Coupled Phase Transitions

马里兰州大学的Sandra Greer教授由理论和计算化学项目资助，对溶液中聚合物的相行为进行实验测量。 许多建议的测量将产生的数据，可用于明确测试最近的理论建议，在聚合物体系中的液-液相分离。 方法包括磁密度法、流变法、张力法和小角中子散射法。 待研究的聚环氧乙烷聚合物系统在广泛的工业中具有重要的应用，并且PEO/溶剂相的表征在许多这些领域中应该是直接感兴趣的。

Professor Sandra Greer of the University of Maryland is funded by the Theoretical and Computational Chemistry Program to perform experimental measurements of the phase behaviors of polymers in solution. Many of the proposed measurements will generate data that can be used to definitively test recent theoretical proposals of liquid-liquid phase separation in polymer systems. Methods include magnetic densimetry, rheometry, tensiometry and small angle neutron scattering. The polyethylene oxide polymer systems to be investigated have important applications in a broad range of industries, and the characterization of PEO/solvent phases should be of direct interest in many of these areas.
