High-Refractive Index Materials

Brewer Science has developed a new approach to the preparation of hybrid coating systems that avoids the problems associated with nanoparticle and sol-gel technologies. In our approach, the high index metal oxide component forms spontaneously during the curing process of the coating, leaving the polymer and metal oxide phases at a near molecular-level of interdispersion. The resulting coatings have refractive indices ranging from 1.65 to as high as 2.15 depending on the metal oxide loading. High refractive index polymer materials currently in development by Brewer Science might be used in applications such as:

• Micro-lens arrays for image sensors
• Cover layer for Optical Storage Disk
• Photonic Crystals
• Holographics
• Waveguides
