论文摘要
我们已经开发了光散射技术的组合，以研究和表征超声波喷雾打印机或飞行中夹具的液滴。对于这种与经济相关的打印机，到目前为止，还没有可靠的技术来系统地调整实验参数。我们已经将光子相关光谱和浊度法结合在一起，以确定液滴的尺寸和速度，具体取决于打印过程的参数作为粘度，浓度和驱动罩气体的速度。我们的方法允许预先确定这些参数可以控制印刷膜的性质，例如从数十纳米到微米的厚度。
We have developed a combination of light scattering techniques to study and characterize droplets of a ultrasonic spray printer or coater in flight. For this economically relevant printer there is so far no reliable technique to systematically adjust the experimental parameters. We have combined photon correlation spectroscopy and turbidimetry to determine size and speed of the droplets depending on parameters of the printing process as viscosity, concentration and speed of the driving shroud gas. Our method allows to predetermine these parameters to control the properties of the printed films as e.g. thickness from tens of nanometers to micrometers.
