Along with the dozens of high-quality technical presentations at the recent AIMCAL R2R Conference Asia in Daejeon, South Korea, a real highlight for me was the tour of the KRICT Chemical Materials Solutions Center (CHEMSOL).
The primary roles of the center are to construct a chemical-materials database and search for its industrial application through data-mining and computer simulation, and to thus develop the R2R coating technologies using solution, sputter and CVD web-coating methods. Overall, CHEMSOL provides lab-scale research, process scale-up and optimization, product design, material suitability, mass production testing, and reliability assessment.
R2R coaters. (Sorry there are no photos, but the systems are all in a working, cleanroom environment.)
- A 650-mm-wide solution web coater with fine-kiss gravure, vacuum slot-die and nanowire-bar methods. A 2-meter x 4-zone floatation dryer and drum-type UV curing are available. The system helps research functional coatings on films for displays, perovskite solar cells, and transparent conductive electrodes for touch panels.
- A 640-mm-wide sputter coater employing 3MF dual and 1DC single magnetrons. Plasma and heating pre-treatment are offered. Applications include index-matching ITO films for touch screens, barriers for flexible displays, and ultra-thin fluorocarbon polymer coating.
- A 500-mm-wide chemical vapor deposition (CVD) system with a microwave plasma source, 0.10-10.0 mpm web speed, and six different precursor gases that can be applied. OPVs, optical coatings, and barriers for flexible displays are tested.
UV-curing multi-coater, cluster-type coater, dual slot-die coater, and a mini R2R solution coater.
