What is Slot-Die Coating?
Compatible with both roll-to-roll and sheet-to-sheet deposition processes, slot-die coating is one of the best techniques available for scalable thin-film deposition. It gives highly accurate film uniformity, has a wide processing window, and is an extremely reliable method for wet thin film coating. The theory behind slot-die coating is very straight-forward; as a pre-metered technique, control of thickness is simply governed by the solution flow rate and substrate speed.
The most important part of any slot-die coating machine is the head, which features a narrow slot through which the solution flows. The rate of flow is precisely controlled to ensure an even coating. TheSIMY- Slot-Die Coater uses a syringe pump to do this, and is capable of producing coatings with variations lower than 5% across large areas and a variation of 0.05% over 100 mm. The wide processing window ensures stable defect-free deposition for various solution viscosities, and the presence of any coating defects can be eliminated by varying several geometric parameters, which do not themselves alter the coating thickness.
There are a significant number of applications for slot-die coating, including:
· Organic Photovoltaics
· Organic Field-Effect Transistors
· Conductive Polymers
· Nanowires and Nanotubes
· 2D Materials
· Organic and Perovskite Light-Emitting Diodes
· Perovskite Photovoltaics
· Electrolytes and electrodes for Li-ion batteries
· Dye-Sensitized Solar Cells
Slot-die coating is the gold standard for scalable thin-film processing. The method is commonly used in manufacturing, and can achieve high coating speeds with excellent accuracy and very little solution waste. The SIMY-Slot-Die Coater brings this to the lab.
Although slot-die coating is an extremely powerful technique, it is primarily considered to be an industrial method. As such, most slot-die coaters are designed to cater to industry rather than academia, and even relatively simple systems come at a high price. These systems are often larger and more complex than what is required by researchers who are just starting to develop the processing techniques required for depositing thin films.
The SIMY-Slot-Die Coater gives researchers access to a slot-die coating, enabling them to optimise ink formulation and processing parameters without the need for large print runs. Ultimately, this helps ensure that their findings can be scaled-up for real-life applications and makes slot-die coater ideal for pilot-level production and scale-up process feasibility tests.
