POROUS COATING LOADED WITH A LIQUID OR A SOLID SUBSTANCE

摘要

The present invention relates to a process for manufacturing a porous coating with controlled structure in the micro or nano-size domain. It characterized by the following steps:
- providing a substrate having a surface,
- depositing on said surface a mono-layer of temporary particles,
- depositing a coating on said surface and on said temporary particles in such a way that the upper part of said temporary particles is not covered by said coating,
- eliminating said temporary particles and thereby obtaining a porous surface,
said process furthermore comprising a coating consolidation step. The invention also concerns objects which can be obtained with this process.
