In this paper, we review the chemical strategies used for the modification of inner surface of

halloysite nanotubes (HNTs). HNTs are nanotubular materials formed by rolling up the 1:1 aluminosilicate clays, where the composition is similar with kaolin. Owing to many virtues, including the high ratio of length to diameter, large cavity volume, desirable biocompatibility and low cost, HNTs have been applied has been applied to numerous promising domains. The modification of outer surface is usually intended to decrease the HNTs dispersal in aqueous media. Considering the selective modification for inner surface gives excellent prospects for hybrid HNTs-based materials, herein we explore the advances in the selective modification of inner surface that expanded the applications of HNTs.
