摘要
综述了粘土矿物对于高吸水性聚合物的改性机理、改性方法的影响,介绍了目前粘土/聚合物复合吸水材料的主要种类。分析指出,吸水能力、凝胶强度与耐盐性三者之间难以统筹兼顾是这类复合材料当前存在的主要问题,将其与天然资源复合开发环境友好型产品,并用于废水中高毒染料和有害金属离子的去除是其今后的发展方向。
The influence of clay minerals on modification mechanism, modification methods of super-absorbent polymer was reviewed. The main types of current existed clay/polymer composite absorbent materials were introduced in the paper. The analysis showed that the main problem of the composite materials was very difficult to coordinate the relation among three factors, such as absorbent ability, gel strength and salt-resistance. The research direction in future is to compose it with natural resources to develop the eco-friendly products and apply them to remove high toxic dyes and harmful heavy metal ions from industrial wastewater.
