Recent Advances on Surface Modification of Halloysite Nanotubes for Multifunctional Applications

Halloysite nanotubes (HNTs) are natural occurring mineral clay nanotubes that have excellent potential application in different fields. However, HNTs are affected by size, surface electron and hydrogen bond formation on the surface which lead to weak affinity and reunion at certain extent. It is very significant to modify the HNTs’ surface to expand its applications. In this review, the structural characteristics, performance and the related applications of surface modification HNTs are reviewed and summarized. We focus on the surface modify methods of HNTs, the effect of surface modification on materials and related applications in various regions. In addition, future prospects and the meaning of surface modification were also be discussed in HNTs studies. This review provided a reference for the application of HNTs modifications in new nanomaterials fields.
