Preparation Note
Typically after this procedure, the material is completely dispersed according to visual observation.
Sonicate 50 mg of material in 5 mL water for 30 min. (A bath sonicator with a sonic power between 45 W and 270 W works fine. A sonic power of 270 W is preferable for faster dispersion).
Add 45 mL of water and sonicate for additional 60 min (or until the material appears well-dispersed).
Dilute the dispersion to the desired concentration and sonicate if necessary. If aggregates are still visible continue to sonicate until satisfactory dispersion is obtained. Note: If unable to achieve a satisfactory dispersion, reduce the initial amount of 50 mg of material in 5 mL of water.
This procedure is to be used as a basis and additional procedures can be researched. Results may vary if this is the first time working with this material. Solubility of this PEG-functionalized SWNTs product can reach 5.0 mg/mL in water.

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.
SWCNTs show promise in FETs, solar cells, and photodetectors due to their ultrafast charge transport mobility.
Carbon nanotubes (CNTs) have received much attention since their discovery in 1991 by Sumio lijima1 due to their excellent mechanical, electrical, and optical properties.
Graphene nanoribbons (GNRs) are quasi-one-dimensional narrow strips of graphene comprised of sp2-hybridized carbon atoms arranged into hexagonal honeycomb lattice configurations.
