Coating is a process that deposits liquid onto a solid substrate. In our research, we have built up three novel coating techniques:
|
| 1. Capillary Coating |
A capillary coater can be considered as a quill in micro-scale, and arbitrary patterns with line width down to 10 μm have been demonstrated.
|
| 2. Air-Bubble Coating |
Air-bubble coating introduces micro-bubbles inside the coater to separate the liquid into segments, which then produces liquid patches with designed line length and line space onto the substrate.
|
| 3. Silicon-Wafer-Based Slot Die Coating |
|
Silicon-wafer-based slot die coater made from standard MEMS process. The coater benefits from the ultra-low surface roughness of silicon wafer and the high precision etching that the polish during conventional coater fabrication process can be completely neglected. The time and cost for manufacturing a slot coating die is thus tremendously reduced, which makes the customization of slot coating die become possible. |
