Superhydrophobic surfaces have been widely studied for their self-cleaning properties. However, most of the constructed superhydrophobic surfaces had problems of changing the surface morphology and color of paper/cloth. An extremely dilute superhydrophobic solution was prepared by hybrid assembly of aminated nano-SiO₂ and high fluorine epoxy polymer P(FOEMA-r-GMA). The preparation of superhydrophobic cotton (SHC) and superhydrophobic book paper (SHBP) was studied through the optimal construction conditions of solution impregnation method. The optimal construction conditions for SHC were as follows: The concentration of fluorinated epoxy polymer was 3 mg/mL, the soaking time was 5 h, the drying time was 8 h, and the drying temperature was 120 °C. The maximum WCA was 158° ± 3°, and the minimum WRA was 4° ± 3°. SHC surface had good hydrophobic effect, acid and alkali resistance, and self-cleaning effect. Additionally, its surface morphology still remained basically unchanged. SHC could be used for oil–water separation with a maximum oil–water separation rate of 98.4%. The optimal construction conditions for SHBP were: The concentration of fluorinated epoxy polymer was 3 mg/mL, the soaking time was 9 h, the drying time was 6 h, the maximum WCA was 155° ± 3°, and the minimum WRA was 6° ± 1°. The hydrophobicity of SHBP was greatly improved; it would extract selective adsorbing oil from the oil–water mixture and slightly reduce its smoothness.

超疏水表面因其自清洁特性而被广泛研究。然而，大多数构建的超疏水表面都存在改变纸/布的表面形态和颜色的问题。通过胺化纳米SiO ₂与高氟环氧聚合物P(FOEMA- r -GMA)的杂化组装制备了极稀的超疏水溶液。通过溶液浸渍法优化施工条件，研究了超疏水棉（SHC）和超疏水书刊纸（SHBP）的制备。 SHC的最佳施工条件为：含氟环氧聚合物浓度为3 mg/mL，浸泡时间为5 h，干燥时间为8 h，干燥温度为120 ℃。最大WCA为158°±3 °，最小WRA为4 °  ±3 °。 SHC表面具有良好的疏水效果、耐酸碱、自洁效果。此外，其表面形貌仍基本保持不变。 SHC可用于油水分离，最高油水分离率可达98.4%。 SHBP的最佳施工条件为：含氟环氧聚合物浓度为3 mg/mL，浸泡时间为9 h，干燥时间为6 h，最大WCA为155 °  ±3 °，最小WRA为6 °  ±1 °。 SHBP的疏水性大大提高；它会从油水混合物中选择性吸附油，并略微降低其光滑度。
