A flexible transparent electrochromic device, which includes the following components, each of which is a flexible film: a working electrode comprising a transparent conducting substrate supporting an working electrode active material; a counter electrode including a transparent conducting substrate supporting a counter electrode active material; a solid polymer electrolyte (SPE) including a solution of a lithium salt in a polymer solvent. A method for preparing an electrochromic device includes the steps of: preparing a working electrode film, preparing a counter electrode film, preparing a polymer electrolyte film, and assembling the electrodes and the electrolyte, the method being implemented continuously.

Flexible transparent electrochomic device, and a method for the preparation thereof

The present invention relates to a method for the preparation of a novel hybrid electrochromic coating material with superior performance in terms of transparency, electrochromic contrast, coloration efficiency, and adhesion, for a use in electrochromic devices for applications where a high transparency is required in the bleached state.

Highly transparent electrochromic coating material, method for producing the same and use of the material

The present invention is directed to an optically clear coating made from a composition comprising an epoxy-melamine resin. The coating is obtained on a metallic substrate and has a very rigid structure and a unique combination of properties that includes hydrophobicity/easy-to-clean, adhesion to bright chrome, abrasion resistance and chemical resistance. The coating composition comprises (A) a mixture of at least one hydrolysable silane and one hydrolysable metal compound, the compounds of said mixture being partly or fully hydrolyzed and partly or fully condensed, (B) at least one melamine derivative selected from derivatives having formula (CN)(NRR), and derivatives having formula (CN)(NRR)(NRR), wherein Rand Rare independently selected from H, hydroxymethylene and alkoxymethylene, with the proviso that at least one of the Rgroups is a hydroxymethylene or alkoxymethylene group, and Ris &#x2014;CH&#x2014;NR(CN)(NRR)or &#x2014;CH&#x2014;O&#x2014;CHNR(CN)(NRR), and p is 1 or 2, and either at least one partially or fully fluorinated, at least partly hydrolyzed and condensed silane compound, this compound being part of the said mixture (A) of hydrolysable silanes, or (C) at least one partially or fully fluorinated organic compound containing at least one group which may bind to hydroxy groups.

Reflectors, for example, for lamps used for technical lighting purposes, having a surface which is resistant to mechanical and chemical attack and has high total reflectivity. The body () of the reflector, which is, for example, a rolled aluminum product such as a foil, a strip of a sheet, has a surface layer in the form of a layer system containing (a) a pretreatment layer (), onto which is deposited (b) a functional layer () with silanes, having organo-functional groups, of a metal compound, and onto which is deposited (c) a metal-containing reflective layer (). Layer (a) is deposited on the reflector body and increases the strength of bonding to the above lying layers (a) and (b). Layer (b) effects a flattening and increase in the mechanical strength of the above lying layer (c). The pretreatment layer can be a layer produced by anodic oxidation. The functional layer (b) can be a sol-gel layer. The reflective layer (c) can be a metallic reflective layer, in some cases with one or more protective layers, which are deposited, e.g., by vacuum thin layer deposition process.

Process for coating surfaces using hybrid polymer materials

The invention concerns composites with excellent barrier properties to gases and water vapor. Such composites can be used, e.g., in foodstuff packaging or as technical membranes. The outstanding barrier effect is achieved by arranging on a substrate material, which, for example, may consist of biodegradable polymers, at least two films. At least one of these films consists of an organic-inorganic hybrid polymer (ORMOCER), at least one further film of a further barrier material or of a substrate material.

The invention concerns a method for producing fluoroalkyl-functionalized hybrid polymer coatings with low surface energy and low tendency to become soiled. Organically modified silanes, metal compounds of formula AlR or MR and at least partially fluorinated organic modified silane serve as components of the coating composition.

Coating material and process for the production of functional coatings

The invention relates to a method of reducing lead release from lead crys glass by applying a coating manufactured by application and hardening of a coating material containing a hydrolytic condensation product comprising a cross-linkable organofunctional hydrosilicon, a metal compound and an organic prepolymer cross-linkable with this hydrolytic condensate.

Reflectors, for example, for lamps used for technical lighting purposes, having a surface which is resistant to mechanical and chemical attack and has high total reflectivity. The body (10) of the reflector, which is, for example, a rolled aluminum product such as a foil, a strip of a sheet, has a surface layer in the form of a layer system containing (a) a pretreatment layer (11), onto which is deposited (b) a functional layer (12) with silanes, having organo-functional groups, of a metal compound, and onto which is deposited (c) a metal-containing reflective layer (13). Layer (a) is deposited on the reflector body and increases the strength of bonding to the above lying layers (a) and (b). Layer (b) effects a flattening and increase in the mechanical strength of the above lying layer (c). The pretreatment layer can be a layer produced by anodic oxidation. The functional layer (b) can be a sol-gel layer. The reflective layer (c) can be a metallic reflective layer, in some cases with one or more protective layers, which are deposited, e.g., by vacuum thin layer deposition process.
