Method to provide a thin film having a chemical composition that is spatially structured on a microscale or nanoscale on a substrate.

摘要

A method of providing a thin film (2) on a substrate (1) in order to obtain a product (9), said film (2) being formed of a material (3), comprising the steps of: - dispersing said material (3) in the substrate material in order to obtain a mixture (10); - molding said mixture (10); - conditioning said mixture (10), said modeling step comprising a step for forming, on a surface (10a) of said mixture (10), protrusions (7) and recesses (6) depending on the intended distribution of the thin film the substrate surface, characterized in that said conditioning step comprises a step of causing said material (3) to emerge on said surface with a higher concentration where protrusions (7) are located, said step of causing said material emerge comprising the step of smoothing said mixture (10) in order to smooth any surface roughness further comprising said protrusions (7).
