摘要:以丙烯酸丁酯与乙烯基硅树脂乳液共聚合成含硅丙烯酸酯疏水乳液。用沉淀法制备 α-Fe 2 O 3 纳米粒子,并
用硅烷偶联剂 KH-560 对其进行表面改性制得 α-Fe 2 O 3 分散液。利用疏水乳液和 α-Fe 2 O 3 分散液对棉织物进行浸
涂,制备超疏水棉织物。采用 XRD、FTIR 和 SEM 对 α-Fe 2 O 3 和超疏水棉织物的结构、形貌进行了表征。考察
了疏水乳液和 α-Fe 2 O 3 分散液浸涂次数对棉织物疏水性能和紫外光照射对超疏水棉织物润湿性能的影响,测定了
超疏水棉织物的油水分离性能。结果表明,用疏水乳液和 α-Fe 2 O 3 分散液分别浸涂 2 次即可使棉织物具有良好的
超疏水性,接触角可达 158.6°。经紫外光照射后,织物正面转变为超亲水状态,反面仍为超疏水状态,棉织物
显示出单向导湿性能。超疏水棉织物对油水混合物中油、水的分离效率分别为 96.1%和 99.0%。

Abstract: Hydrophobic acrylate emulsion with silicone was synthesized by copolymerization of butyl
acrylate and vinyl silicone resin. α-Fe 2O 3 nanoparticles were prepared by precipitation method, and then
silane coupling agent KH-560 was used to modify the obtained α-Fe 2O 3 nanoparticles. Subsequently,
superhydrophobic cotton fabric was prepared by dip-coating of cotton fabric with hydrophobic emulsion
and α-Fe 2O 3 dispersion. The structure and morphology of α-Fe 2O 3 and superhydrophobic cotton fabric were
characterized by XRD, FTIR and SEM. The influence of dip-coating times of emulsion and α-Fe 2O 3
disperse on the hydrophobicity of cotton fabric was investigated. And the influence of UV irradiation on the
wettability of superhydrophobic cotton fabric was studied. Moreover, the oil-water separation performance
of the superhydrophobic cotton fabric was determined. The results showed that the as-prepared cotton fabric
exhibited an excellent superhydrophobicity after two times dip-coating with hydrophobic emulsion and
α-Fe 2O 3 dispersion, respectively, with a contact angle of 158.6°. After UV irradiation, the front side of the
fabric turned to be superhydrophilic, while the reverse side was still superhydrophobic, indicating that the
cotton fabric demonstrated unidirectional moisture conductivity. The separation efficiency of the
superhydrophobic cotton fabric to oil and water in oil-water mixture was 96.1% and 99.0%, respectively.
