Abstract Herein, a simple strategy is presented for the one-pot synthesis of fluorinated oxetanes based on the click reaction between fluorinated thiol and ene groups induced by UV radiation. The final fluorinated product was obtained within 10 min and with a nearly 99 % yield. The cationic ring-opening epoxy polymerization at varying concentrations of these fluorinated oxetanes was conducted using real-time Fourier transform infrared spectroscopy. Compared with traditional post-heating process, the pre-heating process showed higher efficiency and energy saving for the preparation of the final coating. The wettability and hardness of the so-prepared fluorinated coatings were thereafter evaluated. Due to the bicyclic rigid structure, the addition of only 2 mol% FNOX led to an increase in the water contact angle from 64° to 107° and a change in pencil hardness from HB to 4H. Furthermore, improved hardness significantly increased its wear resistance. After 50 abrasion test cycles, the coating retained good hydrophobicity. This synthetic route provides new insights into the potential industrial production of fluorinated coatings on a large scale and at a low cost.

新型氟化氧杂环丁烷的合成与应用

摘要 本文提出了一种基于紫外线辐射诱导氟化硫醇和烯基之间的点击反应一锅法合成氟化氧杂环丁烷的简单策略。最终氟化产物在 10 分钟内获得，产率接近 99%。使用实时傅里叶变换红外光谱法在这些氟化氧杂环丁烷的不同浓度下进行阳离子开环环氧聚合。与传统的后加热工艺相比，预热工艺对最终涂层的制备表现出更高的效率和节能效果。此后评估如此制备的氟化涂层的润湿性和硬度。由于双环刚性结构，仅添加 2 mol% FNOX 导致水接触角从 64° 增加到 107°，铅笔硬度从 HB 变为 4H。此外，改进的硬度显着提高了其耐磨性。经过 50 次磨损测试循环后，涂层仍保持良好的疏水性。这种合成路线为大规模和低成本的氟化涂料的潜在工业生产提供了新的见解。
