전자빔 조사에 의한 실버나노입자 합성과 페이스트 제조 및 물성 연구

Abstract

In this study, a formulation of high conductive paste containing the silver nanoparticles prepared by e-beam irradiation was studied. In order to fabricate the silver nanoparticles, we carried out various experiments. Reaction solution was formulated by adjusting the ratio between DI water, N,N-Dimethylformamide(DMF), Ethanol. Also, silver paste was prepared by controlling the ratio between binders, conductive fillers, and solvents. As a results, optimal particle size was about 70㎚ and resistivity of silver paste was 1.27 x 10-5Ω∙㎝ We expect that e-beam irradiation can be applied to other metallic powder synthesis such as carbon, solder and gold and it can anticipate a possibility of various application in conductive paste fabrication. Also, this work would contribute the commercial application in the field of flexible conductive display and touch panel.
