Allgemeine Beschreibung

Average diameter of individual SWCNT = 1.4nm ± 0.1nm

Anwendung

Method for dispersing in water: In solid form SWNTs are highly entangled and associated in macroscopic particles. It requires significant effort to break such an association and bring the material in solution. Sonicate 50 mg of material in 2 ml water for 30 min. Add 8 ml of water and sonicate for additional 90 min. Typically, after this procedure all material is completely dispersed according to visual observation. For quantitative measurement of the solubility, allow the dispersion to stand overnight at room temperature. Because of the high optical density of concentrated dispersion, dilute an aliquot from the upper layer of the studied dispersion by a factor of 100. The concentration of the diluted solution is estimated from the recorded NIR spectra using a plot of the absorbance at 9750 cm-1 compared to the concentration of a standard solution (see reference).

Poly(aminobenzene sulfonic acid) (PABS) and polyethylene glycol (PEG) were covalently attached to single-walled carbon nanotubes (SWNTs) to form water-soluble graft copolymers. Quantitative near-IR (NIR) spectroscopic studies of these SWNT graft copolymers indicate a water solubility of about 5 mg/mL, and

Manufacturing, Characterization and Use of Single Walled Carbon Nanotubes

Carbon nanotubes are materials that possess remarkable properties and offer extraordinary possibilities.

Sorting Carbon Nanotubes and Their Biological Applications

Carbon nanotubes (CNTs) have received much attention since their discovery in 1991 by Sumio lijima1 due to their excellent mechanical, electrical, and optical properties.

3D Printable Conductive Nanocomposites of PLA and Multi-walled Carbon Nanotubes

A nanocomposite is typically defined as a mixture between a host material (e.g., polymer matrix) and nanofillers with at least one dimension of less than 100 nm.

Polymer-Sorted Semiconducting Carbon Nanotubes for Transistors and Solar Cells

Single-walled carbon nanotubes (SWCNTs) are promising materials for use in the active channel of field-effect transistors (FETs), photoabsorbing layers of solar cells and photodetectors because of their ultrafast charge transport mobility.
