摘要:
A single-walled carbon nanotube composition includes single-walled carbon nanotubes substantially enriched in semiconducting single-walled carbon nanotubes in association with a polymer having one or more oligoether side groups. The oligoether side groups render the composition dispersable in polar organic solvents, for example alkyl carbitols, permitting formulation of ink compositions containing single-walled carbon nanotubes substantially enriched in semiconducting single-walled carbon nanotubes. Such ink compositions may be readily printed using common printing methods, such as inkjet, flexography and gravure printing.

摘要:
Nanoparticle compositions comprising nanoparticles formed from π-conjugated cross-linked polymers are disclosed, together with their methods of manufacture and their applications. Owing to the nature of the cross-links formed therein, the nanoparticle compositions afford a high degree of manufacturing flexibility and control, as well as being amenable to facile purification for the purpose of imaging and electronics applications.
