Optimization Conditions for Single-Walled Carbon Nanotubes Dispersion

The sonication-driven dispersion of single-walled carbon nanotubes (SWCNTs) in aqueous surfactant solution has been monitored by UV-vis-NIR spectroscopy and scanning electron microscopy. Dispersion of SWCNTs experiments reveal that the maximum concentration of dispersed SWCNTs corresponds to the maximum UV-vis-NIR absorbance of the solution. With higher surfactant concentration the dispersion r...

Surfactant-Stabilized Single-Walled Carbon Nanotubes Using Triphenylene Derivatives Remain Individually Dispersion in Both Liquid and Dried Solid States

An easy and simple preparation method for individually dispersed single-walled carbon nanotubes (SWNTs) in both liquid and dried solid states was developed using triphenylene derivatives. Furthermore, highly concentrated solution of SWNTs (0.7-0.8 %) was successfully prepared, and also the SWNTs were dispersed well after the addition of methanol (up to 70 %) for a long time. These properties (r...

The Impact of Sonication on the Surface Quality of Single-Walled Carbon Nanotubes.

Sonication process is regularly adopted for dispersing single-walled carbon nanotubes (SWCNTs) in an aqueous medium. This can be achieved by either covalent functionalization of SWCNTs with strong acid or by noncovalent functionalization using dispersants that adsorb onto the surface of SWCNTs during dispersion. Because the dispersion process is usually performed using sonication, unintentional...

Scalable method for the reductive dissolution, purification, and separation of single-walled carbon nanotubes.

As synthesized, bulk single-walled carbon nanotube (SWNT) samples are typically highly agglomerated and heterogeneous. However, their most promising applications require the isolation of individualized, purified nanotubes, often with specific optoelectronic characteristics. A wide range of dispersion and separation techniques have been developed, but the use of sonication or ultracentrifugation...

AOT dispersed single-walled carbon nanotubes for transistor device application

The precise placement of single-walled carbon nanotubes (SWNTs) in device configurations has been accomplished by AC dielectrophoresis using a biomimetic surfactant, dioctyl sodium sulfosuccinate (i.e. AOT) dispersed SWNTs. To better serve the utilization of SWNTs/AOT for device fabrication, the dispersion of SWNTs in AOT aqueous solutions was investigated at different micellar concentrations a...
