Aquivion® D79-25BS-Li是一种化学稳定的(以S后缀表示)全氟磺酸(PFSA)锂盐分散体,其当量(EW)为790 g/eq。聚合物浓度为25%。溶剂系统的水含量大于99%,不含醚。含水层PFSA锂盐分散液是基于Solvay生产的独特的四氟乙烯(TFE)和磺酰氟乙烯醚(SFVE)F2C=CF-O-CF2CF2-SO2F短侧链共聚物。产生的全氟聚合物的官能团是以其磺酸锂形式存在的,(-SO3LI)。一旦用溶剂配制,Aquivion® D79-25BS-Li可用于在各种基底上制备铸膜或涂层。含有挥发性和非挥发性添加剂的配方可用于制造电化学装置的组件。有关详细信息,请访问aquivion.com。 Aquivion® D79-25BS-Li is a chemically-stabilized (denoted by the S-suffix) perfluorosulfonic acid (PFSA) lithium salt dispersion that exhibits an Equivalent Weight (EW) of 790 g/eq. Polymer concentration is 25 percent. Solvent system is >99% water and is free of ethers. Aquivion® PFSA lithium salt dispersion is based on the unique Short Side Chain copolymer of Tetrafluoroethylene (TFE) and Sulfonyl Fluoride Vinyl Ether (SFVE) F2C=CF-O-CF2CF2-SO2F produced by Solvay. The resulting perfluoropolymer's functional groups are in their lithium sulfonate form, (-SO3Li). Once formulated with solvents, Aquivion® D79-25BS-Li can be used for the preparation of cast films or coatings on various substrates. Formulations with volatile and non-volatile additives can be used to make components for electrochemical devices. Please visit Aquivion.com for more information. |
