高分子薄膜材料在防护涂层、平板印刷、选择性渗透膜、光电器件、数据储存、微反应器等方面有着广泛的应用,材料性能主要取决于其聚集态结构。传统离位研究方法难以描述薄膜所处复杂环境对表界面结构演化的影响,因此开展薄膜受限条件下结构形成动力学机制的研究具有非常重要的科学意义和实际价值。长春应化所科研人员在国家自然科学基金委的国家杰出青年基金和面上项目基金资助下,长期系统地开展了高分子 Macromolecule thin film materials are widely used in protective coatings, lithographic printing, permselective films, optoelectronic devices, data storage, microreactors, etc. The properties of materials mainly depend on their aggregated structure. It is difficult to describe the influence of the complex environment on the evolution of the interface structure of the film due to the traditional method of off-site research. Therefore, it is of great scientific significance and practical value to study the mechanism of structural formation under the condition of thin film.
