A NaCl crystalcoated with plasma-polymerized CTFE hadbeen tested and its IR transmittance onlyreduced 3.2%. It was observed that plasmacopolymerization markedly improved thethermostability of the polymer films.

• 其中淀积了聚合膜的NaCl晶体在26℃温度；84和92%25的相对湿度环境中放置778小时后；其IR透过率仅下降3.；2%25；并且观察到等离子体共聚合大大改善了聚合膜的热稳定性。
