| Summary: | 碩士 === 國立交通大學 === 顯示科技研究所 === 96 === When an inkjet printed deposit is formed, the topography of the droplet on the substrate is of great importance. In order to achieve the droplet geometric controllable process for polymeric dielectrics, a solubility dominated model for suppressing the coffee ring effect was proposed and demonstrated. The solubility can be evaluated by Hildebrand solubility parameter. Line and film with improved morphological control were achieved using the drop spacing optimized method. Printed line and film using this approach can avoid individual droplets and bulge effect. For the electrical performance of printed device, the mobility is of as high as 0.12cm2/Vs. These results demonstrate that our methods are potential to be utilized for fabrication of printed OTFTs.
