摘　　要：为了提高亲水棉织物分离速度、分离效果及增加重复使用次数,采用简单的两步法对亲水棉织物进行表面改性,即先用没食子酸(Gallic acid)和硫酸铜(CuSO_(4))在棉织物表面形成GA-Cu(Ⅱ)络合物改性层,再用十八胺进一步修饰,制备疏水改性棉织物。利用全反射红外光谱对改性后棉织物进行表征,并通过测试改性后棉织物与去离子水的静态接触角来评价其疏水性能。结果表明:在本研究范围内的最佳实验条件为没食子酸浓度12.8 mg/mL、硫酸铜浓度10.0 mg/mL、十八胺浓度8.0 mg/mL,室温下反应4.0 h,改性棉织物与去离子水的接触角为140.9°;改性后棉织物可用于植物油/水混合物和机油/水混合物的分离,分离速度快,效果好,可以多次重复使用。A novel simple two-step method was used to modify the hydrophilic cotton fabrics.Gallic acid(GA)and Copper Sulfate(CuSO_(4))firstly formed a layer of TA-Cu(II)complex on the surface of the cotton fabric,and then further reacted with octadecylamine(ODA)to prepare hydrophobic cotton fabrics.The modification of cotton fabrics was characterized by total reflection infrared spectroscopy.The hydrophobic property of the modified cotton fabrics was evaluated by the surface contact angle of the modified cotton fabric with deionized water.The results showed that the best modifying conditions in this study range were as follows:the concentrations of GA,CuSO4 and ODA were12.8 mg/ml,10.0 mg/ml and 8.0 mg/ml respectively,with the reaction time of 4.0 h at room temperature.The angle of the modified cotton fabric and deionized water was 140.9°.The modified cotton fabrics could be used to separates the mixture of vegetable oil,water and the mixture of engine oil,and water as well speedily and effectively.
