Abstract

Paper plays an important role in various aspects of human life. However, most of the paper materials are vulnerable to both flame and water, which seriously restrict their performance in many applications. Here, we report a new kind of flame-retardant paper with high-temperature-resistant hydrophobicity. This kind of paper was fabricated by vacuum filtration of electrospun fluorinated SiO₂ fibers and methyl silicon resin. It is mechanically flexible. Its Young’s modulus is 94 MPa, similar to normal printing paper. The optimized paper demonstrated a water contact angle (WCA) of 151°, which can be maintained as high as 126° even after 30 min of annealing at the temperature of 600 °C. Finally, writing with inorganic ink can be performed on this paper with inhibited ink diffusion. The written paper can maintain its integrity after 5 min of firing by alcohol flame. The flame-retardant and hydrophobic paper here may extend the applications of paper in wide range of fields.

全氟癸烷掺杂的SiO 2纳米纤维可实现疏水性强的阻燃纸

抽象的

纸在人类生活的各个方面都起着重要作用。但是，大多数纸材料都易受火焰和水的侵蚀，这严重限制了它们在许多应用中的性能。在这里，我们报告了一种新型的耐高温疏水性阻燃纸。这种纸是通过真空过滤电纺氟化SiO ₂制成的纤维和甲基硅树脂。它在机械上是灵活的。其杨氏模量为94 MPa，类似于普通打印纸。优化的纸张显示出151°的水接触角（WCA），即使在600°C的温度下退火30分钟后，也可以保持高达126°。最后，可以在这种纸上用无机墨水进行书写，同时抑制墨水的扩散。酒精火焰烧制5分钟后，书写纸可以保持其完整性。此处的阻燃和疏水纸可以在广泛的领域中扩展纸的应用。
