64‐2: Ink‐Jet Printing of High‐Index Zirconia Nanocomposite Materials

Abstract

High refractive index (RI) nanocomposites have properties which surpass traditional polymers while maintaining manufacturability. Nanocrystal nanocomposites, when inkjetprinted, are useful to many displays and lighting components and aid the development of next generation information devices and lighting fixtures. This paper demonstrates inkjet printing capabilities using high RI, highly transparent PixClear® ZrO 2 nanocrystal dispersions and nanocomposites.

“…The surfaces of the nanocrystals are well-passivated by capping agents, which prevent aggregation and offer compatibility in many different solvents, monomers, and polymers. High weight loadings of nanoparticles, which is required to raise the refractive index to better match that of the anode, can be achieved while still maintaining transparency and the low viscosities necessary for solution processing techniques such as inkjet printing and slot-die coating [187]. Pixelligent is also experimenting with graded index layers to reduce Fresnel reflection as light propagates toward a substrate with lower index.…”
