蒙脱石(MMT)气凝胶具有优异的物理化学性质,如低密度、大比表面积、热稳定性及可调节的表面化学性质,被认为是一种新型功能性气凝胶。近年来,MMT气凝胶作为去除对环境和人类健康构成危害的各种污染物的吸附剂受到了广泛关注。然而,由于机械性能差和吸附能力有限,MMT气凝胶在环境修复方面的应用受到限制。介绍了MMT/天然聚合物复合气凝胶的制备和性能,包括MMT/纤维素复合气凝胶、MMT/壳聚糖复合气凝胶等,综述了MMT/天然聚合物复合气凝胶在水处理中的应用进展并展望了其未来的发展方向。
Montmorillonite (MMT) aerogels exhibit excellent physicochemical properties,such as low density,large specific surface area,high thermal stability,and tunable surface chemistry,and are regarded as a new type of functional aerogel.In recent years,MMT aerogels have attracted extensive attention as adsorbents for the removal of various pollutants that pose risks to the environment and human health.Nevertheless,the application of MMT aerogels in environmental remediation is restricted due to their poor mechanical properties and limited adsorption capacity.This paper introduced the preparation and properties of MMT/natural polymer composite aerogels,including MMT/cellulose hybrid aerogels,MMT/chitosan hybrid aerogels,etc.The research progress in the application of MMT/natural polymer composite aerogels in water treatment was reviewed,and their future development trends were prospected.
