The present invention provides a graded multilayer structure, comprising a support layer (1) and at least 10 layers (2, 3) forming a graded layer, wherein each of the at least 10 layers (2, 3) is at least partially in contact with the support layer (1),
wherein the at least 10 layers (2, 3) differ from each other in at least one property selected from layer composition, porosity and conductivity, and
wherein the at least 10 layers (2, 3) are arranged such that the layer composition, porosity and/or conductivity horizontally to the support layer (1) forms a gradient over the total layer area. The present invention further provides a graded multilayer structure, comprising a support layer (1) and at least two layers (2, 3) forming a graded layer, wherein each of the at least two layers (2, 3) is at least partially in contact with the support layer (1),
wherein the at least two layers (2, 3) differ from each other in at least one property selected from layer composition, porosity and conductivity,
wherein the at least two layers (2, 3) are arranged such that the layer composition, porosity and/or conductivity horizontally to the support layer (1) forms a gradient over the total layer area, and
wherein the overall thickness of the graded layer comprising the at least two layers (2, 3) is more than 5 µm. |
