直写（DW）定义了一组新兴的技术，允许电子和其他功能组件的印刷出真空，直接到保形表面。本项目采用喷墨和喷嘴沉积技术，这两种技术被认为是工业所需的各种材料和加工的互补技术。新癸酸银盐对光源（包括紫外线）和热源都很敏感，溶解在二甲苯中时是良好的喷墨印刷前体。我们研究了喷墨印刷银样品的电性能，衍生自新癸酸银油墨，并研究了在热固化银样品之前的UV处理的影响。在室温下的UV暴露被认为控制银颗粒的成核。此外，我们还研究了热预处理对印刷样品的影响。这种预处理被认为有助于新癸酸酯前体形成均匀分布的银纳米颗粒。报道了玻璃基片的紫外曝光、热预处理和热固化条件对后续径迹微结构的影响及其对电阻率的影响。根据硅油和银浆料的流变特性，进行了不同喷嘴偏置和泵压设置下的挤出实验，寻找出生产连续轨迹的理想条件。这些研究结果被用来模拟计算机模型，以供进一步应用。
Direct Write (DW) defines an emerging group of technologies that allow the printing of electronic and other functional components out of vacuum, directly onto conformal surfaces. Both ink-jet and nozzle deposition technologies, which are seen to be complementary for the wide range of materials and processing required by industry, are employed in this project.Silver neodecanoate salt is sensitive to both light source, including ultra violet light (UV) and heat source, and is a good inkjet printing precursor when dissolved in xylene. We have studied the electrical properties of inkjet printed silver samples, derived from silver neodecanoate ink, and investigated the influence of UV treatment before thermal curing the silver samples. UV exposure at room temperature is believed to control the nucleation of silver particles. In addition we have studied the influence of thermal pre-treatment on the printed samples. This pre-treatment is thought to assist the neodecanoate precursor to form a uniform distribution of silver nanoparticles. The influence of UV exposure, thermal pre-treatment and the thermal curing conditions on subsequent track microstructure, and its influence on electrical resistivity is reported for glass substrates. Furthermore, a series of extruding experimental at different nozzle offset and pumping pressure settings are conducted based on the rheological property of silicone oil and silver paste to find the ideal condition for producing continuous tracks with good shape. These findings are used to simulate a computer model for further applications.
