The Skoltech Laboratory of Nanomaterials, along with the Ural Federal University and the Institute of Engineering Science Ural Branch of the Russian Academy of Sciences, have published findings on how single-walled carbon nanotubes (SWCNTs) can be used to create multifunctional composite structures regardless of their quality when used in extremely small amounts.
An evaporating colloidal particle–laden droplet leaves behind a ring-like residue after drying. We routinely observe this ubiquitous phenomenon for dried coffee drops; thus, it is known as the “coffee-ring effect.” As a droplet evaporates, the edges dry faster than the center, pulling fluid—and suspended particles—outward. This creates a dense ring of material at the periphery of the droplet. It’s a familiar sight to anyone who’s spilled tea or coffee, but for scientists working on coatings and inks, this effect can be frustrating. In many applications, a uniform deposit is far more useful than a ring.
The effective dispersion of carbon nanotubes (CNTs) is critical to their commercial success in applications such as energy storage and polymer composites.
