Abstract

Electrospinning has recently been used for micropatterning. The electrospinning method as a patterning tool has the advantage of a rapid patterning speed because it is based on a continuous printing mode rather than a drop-on-demand mode. To obtain stable continuous printing, a high molecular weight polymer must be mixed with functional materials for patterning. In this paper, polyethylene oxide (PEO) was used. The effect of polymer on viscosity and formation of a Taylor cone jet from the electrospinning nozzle was investigated. Finally, the electrospinning patterning results of a silver paste ink on a glass substrate were investigated.

최근 전기방사를 이용한 프린팅이 미세 패터닝 분야에 응용이 되고 있다. 전기방사를 이용한 패터닝은 연속 프린팅 방식으로 기존의 요구적출형 방식에 비해 패터닝 속도가 빠르다는 장점이 있다. 안정적인 연속 프린팅을 위해서는 고분자의 폴리머를 프린팅하려고 하는 잉크에 혼합하는 것이 필요하다. 본 연구에서는 PEO 를 이러한 첨가 폴리머로 사용하였다. 이러한 폴리머의 첨가에 대한 잉크의 점도 및 Taylor cone 형성에 대해 미치는 영향을 조사하였다. 마지막으로 전기방사 프린팅의 예로서 실버 페이스트 잉크를 유리 기판 위에 패터닝하였다.
