Nanotubes

Presented here is a method for assembling homogenous films of controllable thickness comprised of hybrid nanostructures on a roll-to-roll platform directly from solution. Using surfactant-free mixtures of nanoparticles, nanotubes, nanosheets, and any combination thereof, film fabrication may be achieved that maintains the chemical and physical properties inherit to the constituent material that is not limited by the presence of surfactants or impurities. Using this technique, researchers may demonstrate the viability of scalable production of a synthesized material.

A process for making flexible circuits based on semiconducting carbon nanotube networks and high capacitance ion gel dielectrics through jet printing of liquid inks.

The approach of transferring CNT thin films from one surface to another via a soft lithography technique suffers from limited ability to achieve good adhesion of the CNT films to the transferred substrate and imprecise alignment of the CNT patterns. A transfer technique  that can be scaled to large area with high throughput processing at low temperature is being reported in this paper, demonstrating a scalable means to create aligned CNT thin film patterns on both rigid and flexible substrates.
