應(yīng)用

Nafion^? membrane may be used in the fabrication of electrodes by dry plasma. As a proton exchange membrane Nafion^? has been the focus of considerable efforts to develop improved fuel cells.
Nafion^? is a perfluorinated ion-exchange membrane which has a wide variety of commercial uses. The acidic (hydrogen ion) form and derivatives are solid, superacid catalysts useful in a wide variety of synthetic applications.

Nafion^? 是一種具有廣泛商業(yè)用途的全氟化離子交換膜。其酸性（氫離子）形式和衍生物為可用于許多合成應(yīng)用的固體超強(qiáng)酸催化劑。

包裝

由于有機(jī)物的吸收，在一般室內(nèi)環(huán)境中長(zhǎng)時(shí)間（幾個(gè)月）存放的膜通常會(huì)變暗/變褐色。在儲(chǔ)存期間，應(yīng)確認(rèn)產(chǎn)品是否保持密封。
· 保持膜密封并防止一般暴露，可減少有機(jī)物的影響。長(zhǎng)期儲(chǔ)存時(shí)，建議使用密封袋存放。
· 變色不影響性能，使用稀硝酸浸泡可除去顏色。

Darkening/browning is common for pieces stored in a general room environment for an extended period of time (several months), due to organics pick-up. Verify product is kept sealed during storage.

• Keep pieces sealed and protected from general exposure will reduce the effect. Recommend long term storage in air-tight bags.

• Discoloration does not affect performance and can be removed by soaking in dilute nitric acid.
