U.S.-Czechoslovak Research on the Physics of Polymer Gels

波士顿大学的Rama Bansil博士和捷克斯洛伐克大分子化学研究所的Cestmir Konak博士共同开展的这一美国-捷克斯洛伐克研究项目的主要目标是研究凝胶中颗粒和聚合物的凝胶化和扩散动力学。为了做到这一点，研究人员将添加非常少量的胶体颗粒或将光散射到聚合物溶液中的探针聚合物。后续扩散的测量将使用静态和动态激光光散射。实验结果将通过计算机模拟进行分析，以确定动态过程的细节。研究结果将有助于我们对随机介质中的电泳法和聚合物扩散的基本理解。这一聚合物研究项目通过使美国和东欧的顶尖专家能够将互补的人才结合在一起，并在具有强烈共同兴趣和能力的领域汇集研究资源，实现了促进科学知识发展的计划目标。

The primary objective of this U.S.-Czechoslovakia research project between Dr. Rama Bansil of Boston University and Dr. Cestmir Konak of the Czechoslovak Institute of Macromolecular Chemistry is to study the kinetics of gelation and the diffusion of particles and polymers in gels. To do this the researchers will add a very small concentration of colloidal particles or a probe polymer which scatters light to a polymer solution. Measurements of subsequent diffusion will be made using static and dynamic laser light scattering. The experimental results will be analyzed through computer simulations to determine the details of the dynamic process. Results are expected to contribute to our basic understanding of electrophoresis and polymer diffusion in random media. This project in polymer research fulfills the program objective of advancing scientific knowledge by enabling leading experts in the United States and Eastern Europe to combine complementary talents and pool research resources in areas of strong mutual interest and competence.
