鞘气辅助空气动力学透镜聚焦的干法气溶胶喷印实验研究
Experimental Study of Dry Aerosol Jet Printing with Sheath Gas-assisted Aerodynamics Lens Focusing
摘要
Abstract
To overcome the most important concerns,such as harsh storage conditions and the re-moval of solvents and surfactants in aerosol jet printing(AJP)technology,a nano-powder aerosol printing device with sheath gas assisted aerodynamic lens focusing was proposed,and the aerosol jet printing system was established,and the effects of printing speed,volume flow ratio of sheath gas and carrier gas on printing efficiency and line morphology were explored.The effects of laser treatment on the resistivity,microscopic morphology and oxidation degree of aerosol printing lines were analyzed by laser sintering experiments and electrochemical performance test experiments.Experimental results show that when the printing speed is 19.20 mm/min and the volume flow ratio of sheath gas to carrier gas is 2.65,the minimum width of the printing line is 56.52 μm.After laser sintering,the nano silver powder particles in the printing lines melt and agglomerate and form filaments to bond with each oth-er,which significantly reduces the resistivity of the aerosol printing lines.关键词
