Abstract:Printing technology is considered to be a key technology even in the fields of electronics, materials processing, and biotechnology. However there is a genuine need for nano-to-macro integration technology for printing. This paper presents the fabrication of nanoscale nozzle and patterning by means of electrostatic field induced drop-on-demand inkjet printing system, to overcome the limitation and problem of conventional thermal and piezoelectric print heads described above. When the meniscus of liquid is subject to strong electric field, electric charge is induced on the meniscus and electrostatic force elongates the liquid to form a droplet. The electrostatic field induced inkjet printhead can generate very tiny droplet smaller than nozzle size because the droplet is detached from the tip of the meniscus. Therefore, if we make sub-microscale nozzle, we can generate nanoscale droplets and write any dot, line, or geometries controlling the ejection of the droplet. We fabricated the inkjet head system using the quatrz capillary, and analyzed the electrostatic drop-on-demand ejection from this system. And we can pattern line by using this device.
