Copolymerization approach to control the optical properties of multilayer films
Background Today’s optical devices trigger a need for thinner and lighter optical materials without any compromise in image quality. This has garnered interest in gradient refractive index (GRIN) materials, which can be used for compact optical design and enhance focusing power, correct aberrations, and reduce the number of components needed...

Stretchable and flexible optical interference coatings by polymer multilayers
Background Antireflection coatings (“ARC’s”) minimize undesired lens flare and glare and increase transmission at the interface between an optical material and its medium. While the inorganic fluorides, oxides, and sulfides that presently comprise conventional broadband ARC’s fulfill many if not all of their required functions,...

Methods for Preparing Porous Separators for Electrochemical Cells
Background Porous separators are applied to battery electrodes through roll-to-roll processing. The current industry-standard for polymer separators (Celgard) for lithium-ion batteries (LIB’s) involves relatively involved manufacturing. These materials, fabricated separately from LIB’s, are produced from commodity polyolefin plastics derived...

Class of thin film cathodes based on the solid solution of two layered lithium metal oxide components
Background With the continued evolution of microelectronic devices and their miniaturization, there is significant demand for energy storage devices with reduced dimensions, especially lithium-ion batteries. Solid-state lithium thin-film batteries (TFB’s) possess exceptional energy storage performance with long cycle life, enhanced safety, and...
