Although numerous kinds of waterborne, nacre-mimetic films with excellent properties have been fabricated via different assembly methods, it remains difficult to put those kinds of lightweight materials into practical applications because they are sensitive to water in the environment. Herein, a simple superhydrophobic modification method was used to enhance the repellency of film to water and/or corrosive liquids in the environment. Furthermore, it lowered the gas transmission rate of the films dramatically and improved the heat and flame shield capabilities. This approach could also be applied to other kinds of nacre-mimetic films, proving to be a versatile, low-cost, fast, and facile method to produce large-area and thick, waterborne, multifunctional films with excellent repellency to water and some corrosive liquids in the environment, which will pave the road for the practical applications of nacre-mimetic films.
虽然已经通过不同的组装方法制备了许多具有优异性能的水基、珍珠母仿生膜，但由于它们对环境中的水敏感，因此很难将这些轻量级材料实际应用。在这里，采用了一种简单的超疏水改性方法来提高膜对水和/或环境中腐蚀性液体的排斥性。此外，它还显著降低了薄膜的气体传输率，并提高了其隔热和防火能力。这种方法还可以应用于其他类型的珍珠母仿生膜，是一种通用、低成本、快速和简便的方法，可以生产出具有优异的环境水和一些腐蚀性液体排斥性的大面积和厚的水基多功能膜，为珍珠母仿生膜的实际应用铺平了道路。
