Halloysite Nanotubes in Nanomaterials Research. Halloysite, a naturally occurring aluminosilicate nanotube, has been undeservedly forgotten.
Nanoclays are nanoparticles of layered mineral silicates. Montmorillonite, bentonite, and halloysite nanoclays and organoclays are used in polymer-clay nanocomposites, as rheology modifiers, and drug delivery carriers.
Graphene is a one-atomic-layer thick two-dimensional material made of carbon atoms arranged in a honeycomb structure. Its fascinating electrical, optical, and mechanical properties ignited enormous interdisciplinary interest from the physics, chemistry, and materials science fields.
