Development of "HILUCIS"
Background of Development
Nanoimprint technology enables the precise transfer of nanoscale patterns onto resin substrates, playing a vital role in manufacturing optical devices such as displays, smartphone cameras, AR/VR glasses, facial recognition systems, and autonomous driving sensors. These devices require advanced optical components—like waveguides and diffraction gratings—for light propagation, focusing, and diffraction.
Both glass and resin are commonly used materials for these optical components. Among them, UV-curable resins with high refractive indices have gained attention for their ability to expand viewing angles and improve light control performance while offering greater design flexibility and production efficiency. Common fillers used in high-refractive-index resins include titanium oxide and zirconium oxide. Titanium oxide, while exhibiting high optical activity, can cause photodegradation due to its photocatalytic properties under UV light, potentially compromising the resin's durability. On the other hand, zirconium oxide has a lower refractive index compared to titanium oxide, making it challenging to achieve a refractive index above 1.8 while maintaining sufficient light resistance.
We have developed UV-curing resin with a high level of transparency, exceptional light resistance, and superior nanoimprint compatibility, successfully balancing these properties with a high refractive index.
Technical Breakthrough
HILUCIS addresses these challenges by incorporating a proprietary inorganic filler with low optical activity, minimizing yellowing in the near-UV to visible light spectrum. Leveraging Sanyo Chemical's extensive expertise in designing UV-curable resins for display applications, the resin matrix has been carefully optimized, and HILUCIS achieves a high level of transparency, exceptional light resistance, and superior nanoimprint compatibility, successfully balancing these properties with a high refractive index.
