Abstract: A series of all-liquid, non-filled and halogen free fire-retardant thermosetting resins are herein reported. These compositions provide good physical and mechanical performance while providing inherent nonflammability. The resins systems are designed to eliminate exposure to toxic gases such as halogen halides which are commonly produced during combustion. In addition, due their mechanical performance these materials are capable of excellent performance under high pressure and temperature environments such as those seen by battery enclosures during runaway reactions. In general, these compositions showcase novel fire-retardant resins capable of reducing the risks associated with fires and their byproducts without compromising the utility and performance of such.

Abstract: A method of manufacturing a light-emitting diode device comprises fabricating a light-emitting diode structure comprising an inorganic semiconductor; and fabricating an optic over the light-emitting diode structure using nano-imprint lithography. The method may further comprise, before fabricating the optic, forming a first lens on the light-emitting diode structure by thermal reflow lithography. The optic and first lens may improve the efficiency of the light-emitting diode device by reducing losses due to total internal reflection. Also provided are light emitting diode devices obtainable by the method.
