摘要：
Carbon nanotubes (CNTs)are one of the most representative nanomaterials with excellent performance. Their unique structure combined with their excellent mechanical,electronic and optical properties make them ideal nanomaterials,which are widely used in various fields. However,CNTs have huge surface area and aspect ratio,extremely strong van der Waals forces and π-π accumulation between tubes,which usually exist in the form of parallel tube bundles in the natural state,which greatly hinder the further research and application of CNTs. In recent years,based on the principle of non-covalent chemical modification,people have continuously studied the synthesis of appropriate dispersants for CNTs,explored the mechanism of CNTs dispersion,and attempted to solve the problem of CNTs agglomeration. However,in the field of actual industrial application,the existing scientific research results cannot meet the industrial demand for the dispersion of CNTs. This paper mainly summarized the research progress of polymeric non-covalent dispersants dispersed CNTs,introduced the principle of non-covalent dispersant dispersed CNTs,classified and analyzed the characteristics of dispersion of CNTs in solution and polymer melt. Finally,the research direction of non-covalent dispersants for dispersing CNTs in solution and the design idea of non-covalent dispersants for dispersing CNTs in polymer melt were prospected to expand the application of CNTs in the industrial field. © 2023 Cailiao Daobaoshe/ Materials Review.
