Multifarious Applications of Halloysite Nanotubes: a Review
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...
متن کامل1 Recent Advances on Surface Modification of 2 Halloysite Nanotubes for Multifunctional 3 Applications 4
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,...

Halloysite nanotubes (HNTs) are natural occurring mineral clay nanotubes that have excellent application potential in different fields. However, HNTs are heterogeneous in size, surface charge, and formation of surfacial hydrogen bond, which lead to weak affinity and aggregation at a certain extent. It is very important to modify the HNTs’ surface to expand its applications. In this review, the ...
متن کاملSurface Improvement of Halloysite Nanotubes
A novel development on halloysite-polyvinyl alcohol (HNTs-PVA) nanocomposites has been conducted using malonic acid (MA) by crosslinking PVA and HNTs. PVA-MA crosslinking produces smooth surfaces, which play an important role in enhancing the properties of HNTs-PVA nanocomposite. The crystallographic structures of crosslinked HNTs-PVA show almost no change as depicted by the X-ray diffraction (...
متن کاملDry Sintered Metal Coating of Halloysite Nanotubes
Halloysite nanotubes (HNTs) are a naturally-occurring aluminosilicate whose dimensions measure microns in length and tens of nanometers in diameter. Bonding defects between the alumina and silica lead to net negative and positive charges on the exterior and interior lumen, respectively. HNTs have been shown to enhance the material properties of polymer matrices and enable the sustained release ...
