年度消防总结报告

篇1

摘 要:在前期研究基础上,成功开发出不同结构的膜材料,包括非氟离子交换膜、非氟多孔离子传导隔膜及部分含氟隔膜材料等,并对其构效关系、成膜工艺进行了初步研究。2013年度围绕离子交换膜氧化稳定性降解机理以及多孔离子传导膜的构效关系和非氟离子传导膜规模放大工艺以及放大过程中的基础科学问题展开研究。阐明了非氟离子交换膜的降解机理、掌握了高选择性、高电导率和高稳定性多孔离子传导膜的构效关系,为液流电池离子交换膜的研究提供理论指导。在原创性提出多孔离子传导隔膜的基础之上,成功解决了非氟多孔离子传导隔膜离子选择性与传导性地矛盾,开发出高选择性、高稳定性非氟多孔离子传导隔膜。建立了高性能低成本离子传导膜的合成路线和工艺,确立膜材料的规模放大工艺,在一定程度上解决商业化全氟磺酸离子交换膜价格昂贵、离子选择透过性差等缺点,加快了液流电池的商业化进程。

关键词:非氟离子传导膜 多孔离子传导隔膜 构效关系 离子传输机理

Abstract:Based on our previous studies, membranes with different structures were successfully developed, including non-fluorinated ion exchange membrane, non-fluorinated porous ion conducting membranes, partially fluorinated membranes, and a fundamental study on the structure-property relationship and membrane preparation technology was conducted. In 2013, a series of researches were focused, including the degradation mechanism of ion exchange membrane, the structure-property relationship of porous ion conducting membrane, scaling technology of non-fluorinated ion transport membrane and basic scientific issues during the scaling process. The degradation mechanism of non-fluorinated ion exchange membrane was clarified, and the structure-property relationship of porous ion conducting membrane with high selectivity, high conductivity and high stability was mastered, offering the theoretical support for the development of membranes for flow battery. Based on the concept of porous ion conducting membrane we developed, the conflict between ion selectivity and ion conductivity of non-fluorinated porous ion conducting membrane was successfully resolved, and membrane with high selectivity and high stability was developed. The fabrication technology of ion conducting membrane with high performance and low cost was established, which to some extent overcomes the defects of high cost and low ion selectivity of commercially perfluorinated ion exchange membrane and accelerates the commercialization of flow battery.

Key Words:Non-fluorinate ions exchange membranes;Ions conducting porous membranes;Structure performance relation;Ions transport mechanism
