About
Broadband Reflective Coatings for the Near and Short Wave Infrared using Solution Processable Chalcogenide Hybrid Organic/Inorganic Polymers Tech ID: UA18-225 Invention: High refractive index polymers are used as broad-band infrared reflective coatings in the near and short wave infrared in this invention. These materials are used in multi-layer thin films alternating with low refractive index polymers to create highly reflective IR Bragg reflectors. Coating system design is highly tunable to obtain desired performance using inexpensive, scalable solution processing. Background: Infrared mirrors are used in a variety of applications including imaging, laser mirrors and medical tools. Current limitations to these technologies include cost and opaque properties, limiting their applications. The technology presented here allows for thin, transparent infrared reflective coatings which may be applied using low-cost methods.
Key Benefits
- Inexpensive polymers - Inexpensive application - Thin coatings - Tunable to reflection requirements
Applications
- Hot mirrors (a mirror meant to reflect infrared light back to the source while allowing visible light through) - Bragg reflectors / wave guides - Construction materials for energy-efficient buildings - Heat management - Automotive coatings - Night vision - Thermal imaging
