摘要：
In order to develop cotton based oil-water separation materials with simple process, reusable and high oil-water separation efficiency, and to achieve utilization of waste cotton fabrics with low energy consumption and high added value, hydrophilic flexible MXene nano sheet was applied to cotton fabrics by ultrasonic spraying. With the swelling effect of ionic liquid on the cotton fiber, the surface roughness of cotton fabrics were increased, the fixed loading rate of MXene on cotton fabrics were further improved, and the oil-water separation membrane was prepared. The surface morphology and wettability of oil/water separation membrane were analyzed by scanning electron microscope and contact angle tester. The oil/water separation efficiency, flux, acid and alkali resistance and recyclability of oil/water separation membrane of MXene were tested to evaluate its performance stability in application. The results showed that the separation efficiency of MXene oil/water separation membrane based on cotton fabrics reached 99.1% and remained 98.6% after 10 repeated tests. The separation efficiency has no obvious change in the range of pH 1~13, the contact angle of water in the air is 30°, maintaining 80.1% of the strength of the original cotton fabric. © 2022, Periodical Agency of Journal of Textile Research.
