| Applications | Chemically, the outer surface of the halloysite nanotubes has properties similar to SiO2 while the inner cylinder core is related to Al2O3. The charge (zeta potential) behavior of halloysite particles can be roughly described by superposition of mostly negative (at pH 6-7) surface potential of SiO2, with a small contribution from the positive Al2O3 inner surface.The positive (below pH 8.5) charge of the inner lumen promotes loading of halloysite nanotubes with negative macromolecules, which are at the same time repelled from the negatively charged outer surfaces.
