Abstract

Single-walled carbon nanotubes (SWCNTs) were patterned using inkjet printing. To make the uniform networks of dropped SWCNTs, the effects of substrate heating, surface hydrophilicity of the substrate and the jetting process were investigated. Circuit diagrams including holes, lines and curves were printed on glass and polymer substrates, and the conductive lines were printed on a glass substrate to characterize their electrical properties by I-V curve and impedance measurements. Lines 75 mm long were printed along with the number of overwrites with 150 μm linewidth and width change with five overwrites. As for the results, we confirmed that the dc resistance of the SWCNT line was proportionally changed according to the linewidth and the number of overwrites, and the line feature possessed ohmic characteristics to 2 MHz even after two overwrites.
