Thermophoretic mobility of polymers

该项目的目的是继续和加强申请人和康斯坦丁教授之间已经存在的合作。Morozov在以色列海法的Technion-Israel理工学院休假期间，总共六周。工作重点应放在聚合物的热泳迁移率上。高聚物在溶液中的热泳迁移率与分子量无关。最近，申请人的小组已经表明，对于较短的链，存在与该规则的显著偏离，并且聚合物热泳的相关实体是与Kuhn链段相当的相关单元。申请人和他的主持人已经开始开发一种简单的模型，该模型通过控制小分子混合物中的同位素Soret效应的相同机制来解释刚性聚合物的热扩散系数的普遍值。在访问海法期间，申请人和K. Morozov计划进一步发展聚合物热泳的理论，重新评估申请人小组中测量的数据，并确定未来实验的相关问题。

The aim of the project is to continue and intensify an already existing collaboration between the applicant and Prof. Konstantin I. Morozov during a sabbatical leave of absence at the Technion-Israel Institute of Technology in Haifa, Israel, for a total of six weeks. The focus of the work shall be on the thermophoretic mobility of polymers. The thermophoretic mobility of high polymers in solution does not depend on the molar mass. Recently, it has been shown by the group of the applicant that there is a significant deviation from this rule for shorter chains and that the relevant entities for polymer thermophoresis are correlated units comparable to the Kuhn segment. The applicant and his host have already started to develop a simple model that explains the universal value of the thermal diffusion coefficient of stiff polymers by the same mechanism that governs the isotope Soret effect in mixtures of small molecules. During the visit to Haifa the applicant and K. Morozov plan to further develop the theorie for polymer thermophoresis, to reevaluate data measured in the group of the applicant and to identify relevant questions for future experiments.
