Swcnt Film

An improved layer-by-layer vacuum filtration method was adopted for the fabrication of single-walled carbon nanotube (SWCNT) films aiming at a series of SWCNT films with controllable thickness and density. The electrical transport properties of the multilayered SWCNT films have been investigated. With the constant film density, the decrease of the layer number of the SWCNT film results in an increase of the temperature coefficient of resistance (TCR). SWCNT film with 95% metallic nanotubes has shown a lower TCR than that of the SWCNT films with a low percentage of metallic nanotubes. The effect of thermal annealing and subsequent acid (HNO3) treatment on the electrical properties of the SWCNT films has also been investigated.

The fabrication and characterization of single-walled carbon nanotube (SWNT) multilayers, micropatterns and interconnections on plastic substrates are reported in this paper. The SWNT-based multilayers and devices are fabricated with a simple, fast, inexpensive, low-temperature, and highly efficient technique combining layer-by-layer (LbL) nano self-assembly, microlithography, and lift-off techniques. The SWNT multilayers are alternating layers of SWNTs and poly (dimethyldiallylammonium chloride) (PDDA). Lithography and lift-off techniques are used to pattern the SWNT multilayers. SWNT microstructures with linewidth of 5 μm are fabricated and characterized. The thickness of a (PDDA/SWNT) bi-layer is approximately 76 Å. Two-terminal SWNT thin film based interconnections are fabricated on flexible substrates. Current-voltage (I-V) characterization and four-point probe measurement show that the resistance of the interconnection is nonlinearly inversely proportional to the number of the assembled SWNT layers. The nano-assembled polymer/SWNT composite can be used in many applications due to its low cost, light weight, and long lifetime.
