Physics of Polymer Gels

本研究的主题是研究聚合物凝胶的基本物理，特别是它们的分子结构和微观结构，凝胶化动力学，以及颗粒和聚合物在凝胶中的扩散。探针在凝胶中的扩散问题与电泳的实际问题以及聚合物在随机介质中扩散的基本问题有直接关系。将使用的主要实验工具是静态和动态激光光散射。利用非弹性中子散射和拉曼光谱的凝胶的振动动力学的调查也提出了。实验工作将通过凝胶的计算机模拟来补充。这一努力应导致更好地理解凝胶作为材料的性质。

The subject of this research is to investigate the basic physics of polymer gels, in particular their moleculer and microscopic structure, the kinetics of gelation, and the diffusion of particles and polymers in gels. The problem of probe diffusion in gels has a direct bearing on the practical problems of electrophoresis, and on the fundamental problem of polymer diffusion in random media. The primary experimental tools that will be used are static and dynamic laser light scattering. An investigation of the vibrational dynamics of gels using inelastic neutron scattering and Raman spectroscopy is also proposed. The experimental work will be complemented by computer simulations of gels. This effort should lead to a better understanding of the properties gels as materials.
