Abstract: A photochromic composition having at least one photochromic naphthopyran-based component with R′ and R″ groups selected from hydrogen, alkyl, fluorinated alkyl, alkenyl, alkynyl, alkylaryl, cycloalkyl, alkoxy, halogen, amine, carbonate ester, carboxylate, aryl, substituted aryl, heteroaryl, substituted heteroaryl or a heterocyclic group and Ar′ and Ar″ groups selected from unsubstituted or substituted cyclic five-membered or six-membered structures including benzene, pyridine, thiophene, furan, carbazole, triphenylamine, dibenzothiophene, dibenzofuran, fluorine, naphthalene, anthracene and pyrene. The photochromic composition is excitable under a visible light range to produce a color change. A second photochromic naphthopyran-based component with a different thermal decay rate constant (k) may further be included in the photochromic composition. The photochromic composition is incorporated into color-changing inks and polymers.

Abstract: The present invention provides a lithium metal battery having a lithium metal electrode including a cathode, an anode, a separator positioned between the cathode and the anode, an electrolyte, and a lithium metal negative electrode. The lithium metal negative electrode includes a lithium reactive metal layer, the lithium reactive metal layer being formed on a support conductive layer. A dendrite-suppressing coating is formed over the lithium reactive metal layer; the dendrite-suppressing coating is a displacement-reacted metal including silver reacted from decomposition of a silver salt and having an interface reaction product formed from a reaction between the silver salt and the lithium reactive metal layer. The interface reaction product is positioned between the displacement-reacted metal layer and the lithium reactive metal layer. The dendrite suppressing coating permits lithium metal ions to permeate the coating to react electrolytically in an overall battery reaction.

Abstract: The present invention provides a transparent EMI shielding film that includes a first transparent polymeric substrate layer. A first conductive mesh layer having a first pattern is printed on the first layer, the conductive mesh having a line width from approximately 5 μm to approximately 500 μm and having a space between two adjacent conductive lines of 100 μm to 1000 μm. The conductive mesh blocks electromagnetic signals. A second transparent polymeric layer is positioned over the first transparent polymeric substrate layer having the first conductive mesh layer printed thereon. A second conductive mesh layer having a second pattern is printed on the second transparent polymeric layer, the second pattern being substantially identical to the first pattern, and being substantially identically positioned above the first pattern in order to maximize transparent spaces between adjacent conductive lines. The transparency is approximately 80% or greater in a visible light spectral region.

The present invention also provides a method for preparing the composite.
