Abstract: A foldable ultrathin glass article includes an ultrathin chemically-tempered foldable glass substrate having a thickness of approximately 100 microns or less and a compressive surface stress of at least 100 MPa. A single-layer hard coating is bonded to the first and/or second surface of the ultrathin tempered glass foldable substrate without an adhesive layer. The hard coating includes at least one silsesquioxane having a silicon-oxygen core framework directly bonded to the ultrathin tempered glass foldable substrate. The impact resistance defined by a maximum pen drop height without glass failure is at least four times greater than the ultrathin tempered glass foldable substrate without the hard coating. The hard coating has a surface hardness of at least 7H surface hardness and has a hydrophobic surface with a water contact angle of at least 100°. The coating has a transparency of at least 98 percent compared to uncoated substrates.

Abstract: The invention relates to multi-component shape memory threads, fibers, tubes, or tapes, which includes at least two shape-memory polymeric (SMP-N) components. Each of the at least two SMP-N components is of at least 1% of the total weight, and N is a positive integer starting from 1, and the SMP-N components have a selectively engineered shape recovery temperature (Tr) between approximately 0° C. to 130° C. Also, when TrN and TrN+1 are higher than room temperature, the threads, fibers, tubes, or tapes are configured to assume a substantially helical configuration upon heating to above TrN and lower than TrN+1 by a stimulus when an elongation of the threads, fibers, tubes, or tapes is approximately 30% to approximately 300%, and having a coil diameter from 0.5 to 10 mm and a number of the turns per cm from 5 to 30.

Abstract: An amorphous composite solid electrolyte is provided that includes one or more three-dimensional branched macromolecules with a core portion and at least three arm portions connected to the core portion. Each arm portion includes a random copolymer or a block polymer comprising a first monomer and a second monomer with a molar ratio of the first monomer to the second monomer in the range from greater than 0 to less than or equal to 1. An ion conductive electrolytic solution including at least one lithium salt solution in an amount of approximately 1 mol/l to 10 mol/l is entrained within the branched macromolecule, with a weight ratio of the branched macromolecule to the ion conducive electrolytic solution equal to or lower than 1:9, such that the branched macromolecule has a swelling degree of at least 5:1 (liquid:polymer in weight) of the ion conductive electrolytic solution.

Abstract: The present invention provides a rechargeable lithium-ion battery with an in situ thermally-curable electrolyte. The thermally-curable electrolyte is cured from the thermally-curable electrolyte precursor solution including a first crosslinking agent, a second crosslinking agent, an initiator, an electrolyte solvent, an electrolyte salt, one or more electrolyte additives, and one or more monomers or a monomer polymerization product. The viscosity of the thermally-curable electrolyte precursor solution is below 200 cps such that the thermally-curable electrolyte precursor solution is infiltrated within the separator and the pores inside the cathode and anode layers then cured to form porous separator and porous electrodes fully permeated with a solid electrolyte.

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.
