气溶胶喷射印刷（AJP）是一种多功能技术，适用于使用各种功能油墨的刚性和柔性基材的大面积，精细特征图案。特别是，AJP可以承受1到1000 cP之间的油墨粘度，打印分辨率为10 μ m，因此对柔性和印刷电子产品具有吸引力。这项工作详细调查了与AJP高度相关的油墨基材组合和基材温度的重要方面。为了做到这一点，使用AJP在刚性（玻璃和硅）以及柔性（聚酰亚胺）衬底上印刷薄导电银线。通过测量不同实验条件下的电导率，评估了各种沉积参数与印刷线条“质量”之间的相关性。基于我们的研究结果，提出了一个框架，通过该框架可以控制和评估AJP线的形态，用于大面积和柔性电子设备。
Aerosol jet printing (AJP) is a versatile technique suitable for large-area, fine-feature patterning of both rigid and flexible substrates with a variety of functional inks. In particular, AJP can tolerate ink viscosities between 1 and 1000 cP, with printing resolution of the order of 10 mu m, thus making it attractive for flexible and printed electronics. This work investigates in detail significant aspects of inksubstrate combination and substrate temperature that are highly relevant to AJP. In order to do this, thin conducting silver lines are printed using AJP on both rigid (glass and silicon) as well as flexible (polyimide) substrates. The correlation between the various deposition parameters and the `quality' of the printed lines are evaluated, through measurements of electrical conductivity under different experimental conditions. Based on our findings, a framework is proposed through which the morphology of AJP lines can be controlled and assessed for applications in large area and flexible electronic devices.
