智能复合破乳材料的制备及油水分离性能研究

Oily source of sewage is extensive and the composition is complex, so it is quite difficult to deal with the thorny problem. The traditional method is very effective for the separation of mixed oil-water mixtures, and the separation of emulsified oil-water mixtures (especially for oil-in-water emulsions stabilized by surfactants) is extremely difficult. Therefore, how to effectively separate the oil-water emulsion has become one of the urgent problems to be solved. The project proposed to modify PDVB and PDMAEMA to the stainless steel mesh through a simple method, and surface modification and micro-nano-scale pore size adjustment to prepare ultra-wetting surface. In addition, through the surface grafting to stimulate the response molecules to possess pH, temperature and other hydrophobic conversion function, to achieve the intelligent separation of oil and water emulsion. And further improve the stability of the material to meet the complex oil and water emulsion pollutants treatment, to achieve efficient, economical and green new oil pollutant treatment technology.

含油污水来源广泛，成分复杂，处理起来相当困难。传统方法对不融合的油水混合物的分离十分有效，而对乳化的油水混合物（特别是对由表面活性剂稳定的油水乳液）的分离效果不佳、难度极大。因此，如何对油水乳液进行有效分离成为目前亟需解决的问题之一。本项目拟将PDVB与PDMAEMA通过简单的方法修饰到不锈钢网上，并进行表面修饰及微纳尺度孔径调节来制备超润湿表面。此外，通过表面接枝刺激响应型分子使其具备pH、温度等亲疏水转换功能，实现油水乳液的智能分离。并进一步提高材料的稳定性，满足复杂油水乳液类污染物的处理，实现高效、经济、绿色的新型油类污染物处理技术。
