The present invention relates to a method of preparing a lead-free radiation shielding sheet with excellent shielding performance not only in a high energy (100 kVp) band but also in a low energy (50 to 80 kVp) band and improved durability of the sheet. bands without containing lead. The radiation shielding sheet of the present invention uses antimony (Sb), which has a high shielding rate even in the low energy band instead of lowering the content of tungsten having a relatively lower shielding rate in the low energy band than in the high energy band, thereby increasing the shielding performance in both high energy (100 kVp) and low energy bands. Further, the radiation shielding sheet of the present invention may increase not only durability, but also elasticity, tearing strength, and tensile strength by mixing additives such as zinc oxide with the rubber.

A component is provided for an aircraft. This aircraft component includes an object and a multi-layer coating. The object includes an object surface. The multi-layer coating includes a barrier layer and a laminar flow layer. The covers at least a portion of the object surface. The barrier layer a fluoropolyether, a silicon rubber and/or a polyurethane. The laminar flow layer covers the barrier layer and forms an exterior surface of the component. The laminar flow layer includes a sol-gel siloxane, a rare-earth oxide and/or a phosphate.

Ceramic-polymer film includes a polymer matrix, plasticizers, a lithium salt, and a ceramic nanoparticle, LLZO: Al.sub.xLi.sub.7-xLa.sub.3Zr.sub.1.75Ta.sub.0.25O.sub.12 where x ranges from 0 to 0.85. The nanoparticles have diameters that range from 20 to 2000 nm and the film has an ionic conductivity of greater than 1×10.sup.−4 S/cm (−20° C. to 10° C.) and larger than 1×10.sup.−3 S/cm (≥20° C.). Using a combination of selected plasticizers to tune the ionic transport temperature dependence enables the battery based on the ceramic-polymer film to be operable in a wide temperature window (−40° C. to 90° C.). Large size nanocomposite film (area ≥8 cm×6 cm) can be formed on a substrate and the concentration of LLZO nanoparticles decreases in the direction of the substrate to form a concentration gradient over the thickness of the film. This large size film can be employed as a non-flammable, solid-state electrolyte for lithium electrochemical pouch cell and further assembled into battery packs.

Described herein are methods for improving the color stability of a synthetic polymer composition by incorporating one or more inorganic phosphor dopants into the synthetic polymer. The inorganic phosphor dopants absorb UV light and emit the UV light as down-converted visible light, thereby producing a brighter appearance for the synthetic polymer composition. Methods for preparing the synthetic polymer compositions having improved color stability are additionally described.
