| 摘要 |
The present invention provides a graded multilayer structure, comprising a support layer (1) and at least two layers (2, 3), 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, and
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. |
