摘要:
The invention relates to a method of manufacturing a coated polymer substrate having low emissivity properties and a high hardness. The method comprises the steps of providing a polymer substrate; applying at least one adhesion promoting layer on one side of said polymer substrate; applying at least one silica or silica-based layer on said at least one adhesion promoting layer by a sol-gel process. The invention further relates to a coated polymer substrate having low emissivity properties, to a glass substrate provided with a coated polymer substrate and to the use of such a coated substrate as substrate having low emissivity properties.
摘要:
The invention relates to a process for preparing a porous material comprising metal, metalloid, or non-metal precursor, said process comprising the steps of: - dispersing the porous material in a hydrophobic solvent; - adding a metal, metalloid, or non-metal precursor solution in a hydrophilic solvent to the dispersed porous material and the hydrophobic solvent, thereby forming a mixture; and - selectively removing the hydrophilic solvent from the mixture; thereby impregnating the porous material with the metal, metalloid, or non-metal precursor solution; thereby preparing a porous material comprising metal, metalloid, or non-metal precursor. The process may additionally comprise a step of converting the precursor, and a step of removing the porous material. Also described is a nanostructured metal, metalloid, or non-metal decomposition product; or metal, metalloid, or non-metal; or metal, metalloid, or non-metal oxide. ln a preferred embodiment, nanostructured bismuth is prepared using mesoporous silica or mesoporous titania as the porous material, viz. template.
