溶剂小分子在高分子中的传质研究评述

Analysis of Solvent Mass Transfer Behaviors in Polymers

溶剂在高分子中的传质涉及化工、材料、医药等多个领域,对其进行研究可扩充以研究小分子为主的传统传质理论,并可为传统产业、制药工业、资源利用和环境保护以及新能源开发带来直接经济效益。溶解性和扩散性是描述溶剂在高分子中传质现象的两个关键因素。文中分析了溶剂在高分子中传质研究的意义,结合该实验室的课题研究成果,对溶解性模型和扩散性模型的发展进行较为详细的综述,并指出其发展方向。

The solvent mass transfer behaviors in polymers exist universally in many fields such as chemical engineering, material, medicine, and so on. The study on such diffusion phenomena can extend conventional transport theory which focuses mainly on transport of small molecules, weanwhile bring commercial benefits to traditional industry, pharmaceuticals industry, resource utilization, environment protection, and development of new energy. Solubility and diffusivity are two key factors in the description of mass transport phenomena in polymer solutions. In this paper, the significant importance of research on solvent transport behaviors in polymers was analyzed, the development of solubility and diffusivity models including recent research in our lab were reviewed in details, and the future development of these two kinds of models was also pointed out.
