Direct Aqueous Dispersion of Carbon Nanotubes Using
Nanoparticle-Formed Fullerenes and Self-Assembled Formation of p/n
Heterojunctions with Polythiophene
Posted on 2017-04-25 - 08:14
Single-walled
carbon nanotubes (SWCNTs) have received much attention
because of their potential in optoelectronic applications. Pristine
SWCNTs exhibit substantial van der Waals interactions and hydrophobic
characteristics, so precipitation occurs immediately in most organic
solvents and water. Highly toxic and hazardous chemicals are often
used to obtain well-dispersed SWCNTs. Developing environmentally friendly
processing methods for safe and practical applications is a great
challenge. Here, we demonstrate direct exfoliation of SWCNTs in pure
water only with n-type semiconducting fullerene nanoparticles. The
resultant SWCNTs can be well-dispersed in water, where they remain
essentially unchanged for several weeks. Adding an aqueous solution
of p-type semiconducting water-soluble polythiophene yields self-assembled
p/n heterojunctions between polythiophene and the nanoparticles. The
aqueous-dispersed SWCNTs yield photocurrent responses in solution-processed
thin films as a potential application of water-dispersed carbon nanomaterials.
