University of California, Riverside, scientists have added ionic liquid to single-walled carbon nanotubes and modified the optical transparency as a result.
Ionic liquid contains negative and positive ions that can interact with nanotubes, dramatically influencing their ability to store and electric charge.
Carbon nanotubes are about 1,000 times smaller than a single hair stand and therefore very little is needed to cover large areas.
Scientists still need to study nanotube film viability for application in compact analytical instruments like spectrometers.
