Abstract

Ionic liquids (ILs)-based organic–inorganic nanocomposite materials are a new class of hybrid materials which can be used in lithium batteries, fuel cells, dye-sensitized solar cells and pressure sensors. Halloysite nanotubes (HNTs, Al₂ Si₂O₅(OH)₄·nH₂O) are hollow like aluminosilicate clay, similar to commonly used platy clay kaolin, which open up various attractive applications including catalysis, anticorrosion, adsorbent, drug delivery, enzyme immobilization, fiber spinning and so on. However, the inorganic characteristics of clay-based halloysite nanotube result in a limited application in electronic field, making it difficult to capture attentions as extensively as carbon nanotubes. Herein, we develop a feasible and versatile approach to prepared ILs grafted HNTs, by coupling the arylboronic acid and Al-OH groups on the HNTs. ILs are grafted to the modified HNTs via a typical atom transfer radical polymerization (ATRP) method. The modified halloysite nanotubes (HNTs) are characterized by (FTIR), thermogravimetric analysis (TGA), scanning electron microscopy (SEM) and transmission electron microscope (TEM).
