研究表明，通过1,3-偶极环加成对碳纳米管（CNTs）进行共价官能化是一种有效的方法，可以增强碳纳米管的加工能力，促进杂化复合材料的制备，而这只能通过混合来实现。碳纳米管被苯酚基团功能化，在包括水在内的一系列极性溶剂中提供稳定的分散体。此外，功能化的碳纳米管可以很容易地与聚合物和层状铝硅酸盐粘土矿物结合，形成均匀、相干、透明的碳纳米管薄膜和凝胶。
We show that covalent functionalization of carbon nanotubes (CNTs) via 1,3-dipolar cycloaddition is a powerful method for enhancing the ability to process CNTs and facilitating the preparation of hybrid composites, which is achieved solely by mixing. CNTs were functionalized with phenol groups, providing stable dispersions in a range of polar solvents, including water. Additionally, the functionalized CNTs could easily be combined with polymers and layered aluminosilicate clay minerals to give homogeneous, coherent, transparent CNT thin films and gels.
