1999: Nanocapillarity: Wetting of Carbon Nanotubes
It is well documented in the modem literature that the conventional laws of capillarity such as Laplace, Kelvin, and Young-Dupre equations are not adequate when applied to fluids confined by particulate and porous materials. Specifics of interactions of fluids with solid surfaces at the nanoscale are of special engineering importance in view of recent discovery of carbon nanotubes and rapidly g...
متن کاملPolymer nanotubes by wetting of ordered porous templates.
We have developed a simple technique for the fabrication of polymer nanotubes with a monodisperse size distribution and uniform orientation. When either a polymer melt or solution is placed on a substrate with high surface energy, it will spread to form a thin film, known as a precursor film, similar to the behavior of low molar mass liquids (1, 2). Similar wetting phenomena occur if porous tem...
متن کاملElectronic sensitivity of carbon nanotubes to internal water wetting.
We have constructed devices in which the interior of a single-walled carbon nanotube (SWCNT) field-effect transistor acts as a nanofluidic channel that connects two fluid reservoirs, permitting measurement of the electronic properties of the SWCNT as it is wetted by an analyte. Wetting of the inside of the SWCNT by water turns the transistor on, while wetting of the outside has little effect. T...
متن کاملNanotubes à la carte: wetting of porous templates.
Nanotubes have an outstanding potential both for applications in nanotechnology and as the subject of basic research. Wetting of porous templates is a simple technique that overcomes many limitations of established preparation methods. It extends the range of processable materials, for example, by a broad range of multicomponent mixtures or by high-performance polymers such as poly(oxy-1,4-phen...
متن کاملStatic and dynamic wetting measurements of single carbon nanotubes.
Individual carbon nanotubes were immersed and removed from various organic liquids using atomic force microscopy. The carbon nanotube-liquid interactions could be monitored in situ, and accurate measurements of the contact angle between liquids and the nanotube surface were made. These wetting data were used to produce Owens and Wendt plots giving the dispersive and polar components of the nano...
