Temperature Dependent Resistance of Multi Wall Carbon Nanotube By Inkjet Printing
Abstract:We present the fabrication and the characterization of temperature-sensitive resistors made by inkjet printed multi-wall carbon nanotube (MWCNT) network films. Centrifuged aqueous solutions of with 0.5 wt.% MWCNT was used to perform a stable drop ejection without nozzle clogging. Single nozzle piezoelectric inkjet heads with 50 micron inner diameter were used to print resistor patterns with a size of 0.3 × 5 mm up to 16 layers on Pyrex glass substrates. The samples were annealed in a tube furnace with or without air at various temperatures. High density network films of MWCNT were fabricated. All the samples show linear I-V relationship and the conductance was almost proportional to the number of layers. The resistance decrease with the annealing temperature slightly. For the samples annealed in the air, the temperature dependence on the resistance was relatively stable.

For more than 25 years, NIP has been the leading forum for discussion of advances and new directions in non-impact and digital printing technologies. A comprehensive, industry-wide conference, this meeting includes all aspects of the hardware, materials, software, images, and applications associated with digital printing systems, including drop-on-demand ink jet, wide format ink jet, desktop and continuous ink jet, toner-based electrophotographic printers, production digital printing systems, and thermal printing systems, as well as the engineering capability, optimization, and science involved in these fields.
Since 2005, NIP has been held in conjunction with the Digital Fabrication Conference.
