Nanopaper prepared from cellulose nanofibers (CNFs) is a kind of promising substrate for various high-tech devices. However, several drawbacks including poor water stability and weak corrosion resistance still remain, which limit the practical applications of the nanopaper. Herein, we present a simple and low-cost method for fabricating transparent and superhydrophobic nanopaper by spraying fluorinated silica/multi-walled carbon nanotubes (SiO/MWCNTs) composite on the nanopaper. A series of functional nanopaper were fabricated, which shows excellent performance of water repellency, chemical stability, conductivity, thermostability and self-cleaning property. Among them, the nanopaper modified with the composite containing 0.5 wt% MWCNTs has a water contact angle of about 163°, transparency of 79.96% and the sheet resistance of 3.15 × 10 Ω sq. The combination of the promising features in a material offers attractive prospects, and enables our nanopaper could be tailored for emerging applications such as flexible electronics, display protection and intelligent packages.
由纤维素纳米纤维 (CNFs) 制备的纳米纸是一种很有前途的各种高科技设备的基底。然而，包括较差的水稳定性和较弱的耐腐蚀性在内的几个缺点仍然存在，这限制了纳米纸的实际应用。在此，我们提出了一种简单且低成本的方法，通过在纳米纸上喷涂氟化硅/多壁碳纳米管 (SiO/MWCNTs) 复合材料来制备透明超疏水纳米纸。制备了一系列具有不同功能的纳米纸，它们表现出优异的拒水性、化学稳定性、导电性、热稳定性和自清洁性能。其中，用含有 0.5wt%MWCNTs 的复合材料改性的纳米纸的水接触角约为 163°，透光率为 79.96%，面电阻为 3.15×10 Ω sq。这种材料在一个单一的产品中结合了多种有前景的特性，为新兴应用提供了有吸引力的前景，使我们的纳米纸能够针对灵活的电子产品、显示保护和智能包装等新兴应用进行定制。
