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.
