Abstract

Abstract This paper deals with the structure and chemistry of Nafion-H, the acidic form of Nafion, which is the trade name for a perfluorinated polymer manufactured by E. I. du Pont de Nemours & Co., Inc. Nafion-H and its salts are available from Dupont in both membrane and powder forms. Nafion composites with Teflon mesh (polytetrafluoroethylene) added to give increased mechanical strength are also available. In addition, sulfonated fluorocarbons modified with other chemically active polymers have been made by Dupont and by competing companies such as Ashai Chemical Industry Co., Ashai Glass Co., Tokuyama Soda Co., and Toya Soda Co.

氟化磺酸聚合物nafion-h的结构和化学性质
摘要本文研究了Nafion- h的结构和化学性质,即Nafion的酸性形式,Nafion是e.i.杜邦德内穆尔公司生产的全氟聚合物的商品名称。氢离子及其盐类可从杜邦公司获得膜和粉末两种形式。加入特氟龙网(聚四氟乙烯)以增加机械强度的Nafion复合材料也是可用的。此外,杜邦公司及其竞争对手,如旭化学工业公司、旭玻璃公司、德山汽水公司和托雅汽水公司,已经生产出用其他化学活性聚合物改性的磺化氟碳化合物。
