Integration of Ink Jet and Transfer Printing for Device Fabrication Using Nanostructured Materials

低黏度的碳油墨容易产生流动、延展和干燥不均匀等问题，这给喷墨印刷技术提出了挑战。本文提出的一种多孔、平面式印模综合了喷墨印刷和转移印刷的优点，可实现含有纳米线、纳米管、纳米粒子和生物分子的稀释油墨进行印刷。

Low viscosity, dilute inks of carbonaceous materials that tend to run, spread, and dry unevenly pose a major challenge towards inkjet printing approaches. A porous, planar stamp based methodology outlined here combines the advantages of inkjet ＆ transfer printing while enabling printing of dilute inks comprising nanowires, nanotubes, nanoparticles, and biological molecules. Integration of inkjet and transfer printing is reported with agarose gel planar stamp, for carbon nanotube inks, enabling the formation of gate modulated channels between source and drain electrodes without necessitating any lithography steps.
