Abstract: Considering their peculiar properties, nanometer materials can be embedded into polymeric membrane to obtain nanocomposite membranes that could help to solve the “trade-off effect”, which has restricted the development of membrane technology. In recent years, a variety of nanometer materials have been applied in the preparation of nanocomposite membranes. This review summarizes the researches of nanocomposite membranes involving nanomaterials such as carbon nanotubes, graphene, SiO2, TiO2, molecular sieve, ZrO2 and silver nanoparticles in the field of membrane separation. The nanometer materials can significantly improve the mechanical stability, hydrophilicity, selectivity, permeability and anti-pollution capacity of composite membranes. The perspectives of the development and application of nanocomposite membranes were proposed and the existing problems and solutions in this field were also presented.

Key words: nanocomposite membrane, membrane separation, membrane technology, nanomaterials, membrane performance
