Natural tubules Halloysite are unique and versatile material formed by surface weathering of aluminosilicate minerals and comprises of different proportion of aluminum, silicon, hydrogen, and oxygen. It has chemical formula of Al4Si4O10(OH)8 4H2O. Nanotubular geometry of halloysites exhibit nanoscale dimensions. Basically, this tubular arrangement varies with different regions. HNTs have high m...

The pencil hardness of a two-component polyurethane coating was improved by adding halloysite nanotubes to the recipe at a weight fraction of less than 10%. The pencil hardness was around F for the unfilled coating and increased to around 2H upon filling. It was important to silanize the surface of the filler in order to achieve good coupling to the matrix. Sonicating the sample during drying a...

Currently, the most promising approach in the corrosion protection of smart coatings is the use of nanoreservoirs loaded with corrosion inhibitors. Nanocontainers are filled with anti-corrosive agents and are embedded into a primer coating. Future prospective containers are halloysite nanotubes (HNTs) due to their low price, availability, durability, with high mechanical strength and biocompati...

Halloysite nanotube supported ruthenium catalyst was prepared by an easy and reproducible in situ bottom up approach. Ruthenium (III) chloride reduced sodium borohydride the presence of halloysite nanotubes dispersed water. Several analyses confirm immobilization particles onto aluminosilicate support. The synthesized then tested hydrogenation 1-hexadecene, a highly hydrophobic compound, aqueou...

Halloysite nanotubes (HNTs) are natural occurring mineral clay nanotubes that have 11 excellent potential application in different fields. However, HNTs are affected by size, surface 12 electron and hydrogen bond formation on the surface which lead to weak affinity and reunion at 13 certain extent. It is very significant to modify the HNTs’ surface to expand its applications. In this 14 review,...
