| 摘要: |
| 以壳聚糖、微米氧化铝为改性原料,以不锈钢筛网为基体,通过浸渍涂覆的方法制备系列改性筛网,采用扫描电镜、接触角测量仪对改性筛网进行表征。考察刻蚀时间、壳聚糖质量分数、氧化铝质量分数、氧化铝粒径、重复使用次数等因素对改性筛网水下亲水/疏油性能的影响,研究改性筛网的性能。结果表明,制备的改性筛网具有良好的水下亲水疏油性,可分离不同类型的油水混合物,具有良好的耐盐和耐碱性能。 |

| Abstract: |
| A series of modified mesh were prepared by dipping coated method with chitosan and micron-alumina as raw material and stainless steel mesh as substrate. The modified stainless steel meshes were characterized by scanning electron microscope (SEM) and contact angle tester. The influence of the etching time, chitosan concentration, micron-alumina concentration of micron-alumina size and the cycle number hydropjilicity/oleophobicity underwater of modified meshes were studied. The results demonstrate that the modified stainless steel meshes have an excellent hydrophilicity/oleophobicity underwater property and it can separate different types oil-waters, which maintains nice hydrophilicity/oleophobicity property in alkaline solution and saline aqueous. |
| Key words: chitosan micron-alumina stainless steel mesh hydrophilic and oleophobic underwater contact angle separation efficiency |
