“…Successful grafting of organic moieties can be evidenced by dispersing unmodified and modified nanotubes in organic solvents ( Figure 5.8) [131,135,137]. Grafting of carboxylates [128,138,139] and sulfonates [140] groups have also been reported with similar results as with phosphonates. Otherwise, the use of silane as coupling agent appears to be controversial because the moieties remain hydrolytically labile and are totally removed after several days of dialysis [141,142].…”

Hollow cylinders with a diameter in the nanometer range are carving out prime positions in nanoscience. Thanks to their physico-chemical properties, they could be key elements for next-generation nanofluidics devices, for selective molecular sieving, energy conversion or as catalytic nanoreactors. Several difficult problems such as fine diameter and interface control are solved for imogolite nanotubes. This chapter will present an overview of this unique class of clay nanotubes, from their geological occurrence to their synthesis and their applications. In particular, emphasis will be put on providing an up-to-date description of their structure and properties, their synthesis and the strategies developed to modify their interfaces in a controlled manner. Developments on their applications, in particular for polymer/imogolite nanotubes composites, molecular confinement or catalysis, are presented.

“…Similar to phosphonates, the carboxylates and sulfonates moieties are reported to strongly interact with the -Al-OH groups of INTs [84], resulting in homogeneous hydrogels exhibiting thixotropic behavior [93], hierarchical ordering [94] and modified optical properties [95]. Grafting of other functional groups have also been reported, using chemisorption [96,97], chemical vapor deposition (CVD) [98,99], or γ-ray irradiation, the latter being used to generate peroxide groups for subsequent monomer polymerization) [100,101].…”

Among a wide variety of inorganic nanotubes, imogolite nanotubes (INTs) represent a model of nanoplatforms with an untapped potential for advanced technological applications. Easily synthesized by sol-gel methods, these nanotubes are directly obtained with a monodisperse pore size. Coupled with the possibility to adjust their surface properties by using straightforward functionalization processes, INTs form a unique class of diameter-controlled nanotubes with functional interfaces. The purpose of this review is to provide the reader with an overview of the synthesis and functionalization of INTs. The properties of INTs will be stated afterwards into perspective with the recent development on their applications, in particular for polymer/INTs nanocomposites, molecular confinement or catalysis.

“…109,112,117 As the substrate of imogolite/WS-PPP LbL film, mercapto groups were introduced onto the surface of Piranha-treated silicon wafer by chemical vapor adsorption of 3-mercaptopropyl-trimethylsilane (MTS) and then the mercapto groups were converted into sulfonic acid groups, which can form electrostatic interactions with fibrous imogolite. 118 Besides planar substrates, there are also some reports using fibers as substrates, such as cotton fabric 108,113 and alkali extracted fibers (AEF). 119 The LbL film modified fibers had higher thermal stability compared to the material without modification.…”
