Advancing Electrochromics with Slot-die Coating

Electrochromics is a technology that enables materials to change their optical properties—such as transparency, reflectivity, or color—in response to an applied electrical voltage. These materials are used in smart windows, adaptive displays, rearview mirrors, and other applications where variable shading or visibility control is desired. By allowing dynamic modulation of light and heat, electrochromic devices contribute to greater comfort, energy efficiency, and design flexibility across architectural and automotive industries. The performance and reliability of these devices, however, depend not only on the materials themselves but also on how precisely they are deposited as thin films. Slot-die coating plays a key role in this aspect, providing the accuracy and consistency required to produce electrochromic layers with uniform thickness, smooth morphology, and excellent optical quality.

Advancing Research and Material Innovation

Slot-die coating provides precise control over electrochromic layers, enabling researchers to explore how thickness, composition, and structure affect switching speed, optical contrast, and device lifetime. Its repeatable, small-scale deposition makes it ideal for prototyping and testing new materials like tungsten oxide, nickel oxide, and conductive polymers. This capability accelerates the development of next-generation electrochromic systems and translates lab discoveries into functional, reproducible devices.
