中文摘要： 用印刷方式制备由纳米材料构筑、堆叠结构清晰、空间结构准确的多层材料结构是实现高质量功能材料印刷的关键所在。其核心在于对印刷动力学特征的准确描述以及有效操控。本项目的具体目标包括：建立适用于功能材料的印刷动力学模型；将印刷动力学理论模拟与先进的材料制备与检测技术相结合, 系统地研究印刷参数、承印表面(包括未印基材表面和已印表面)的物理和化学性能以及墨液的流变特性对印刷动力学的影响；将纳米材料(纳米粘土、纳米纤维素等)用印刷方式涂布到承印表面、实现对承印表面的局部改性(局部亲水、厌水性的调节)；从而实现对功能印刷动力过程的有效操控。本项目的研究结果不仅对实现高印刷精度（高分辨率）、性能优异的印刷电子有重要科学意义；同时为降低印刷电子成本: 将纳米导电材料、有机导电材料与介电材料等直接印制到包装材料（例如包装纸版）表面，为实现印刷电子与色彩印刷一体化奠定坚实基础。

英文摘要： The main focus of this project is to develop printing dynamics model and experimental means， which enable an effective control of printing & ink dynamics in the field of functional printing as for instance printed electronics. The outcome of this project will form the ground for creating high-definition printed electronics, a functional material stack with well-defined material structure and size. The dynamics of printed functional ink is an instant (millisecond) yet very complicated process involving several physical and chemical processes that occur simultaneously or sequentially. This dynamic process is influenced by printing methods and printing settings such as speed of the print. It is also influenced by the physical and chemical properties of the materials involved, substrates and inks. Such as, surface topology，surface energy of the bare substrate and/or the already printed areas on which it will be printed; surface tension and viscosity of the ink, to mention some. A printed functional device is usually of a multilayer material stack, consisting of, for example, conductive and dielectrical materials. To gain an effective control of the material-deposition processes, including material compositions, thickness and sizes of each material layer (resolution and precision), is one of the major challenges that the printed electronics are facing today. In the envisaged project we will perform systematic studies to generate knowledge on how the performance of the printed electronics is affected by the materials properties or combinations of materials properties as well as printing technologies and printing settings. The methods we use will be a combination of theoretical simulations with advanced technologies for modifying material properties and further with advanced measurement/detecting technologies. We will also develop the route how to utilize nano materials, for instance, nanoclays, nano-fibrill cellulose,etc. to modify the surface properties for improved printability and controlled ink-deposition processes by means of pre-patterning the nano materials with flexography and/or inkjet technologies.
