The colloidal stability of halloysite clay nanotubes dispersion is reviewed showing the strategy and the mechanism to obtain stable systems in water and apolar solvents. The selective modification of halloysite inner/outer surfaces can be achieved by exploiting electrostatic interactions. The ad...detailed

By X-ray diffraction, thermal analysis, diffuse reflectance infrared spectrometry, solid state nuclear magnetic resonance (1H and 29Si), and transmission/high-resolution transmission electron microscopy, silanization of heat-treated halloysite samples (300–1200 °C calcination) using γ-aminopr...detailed

In this study, the interfacial tension behavior of halloysite nanotube (HNT) as a hydrophilic nanoparticle and modified APTES-HNT as a hydrophobic nanoparticle at the palm oil-water interface was investigated. The result of this study was used to determine the stability and potential formation o...detailed

Halloysite clay is a natural nanomaterial that is attracting a growing interest in colloidal science. The halloysite aqueous dispersion stability is a key aspect for the configuration of a purification protocol as well as to establish the durability of a formulation. A physico-chemical study dem...detailed
