Abstract
The present invention relates to a process for manufacturing a porous coating with structures in the micro or nano-size domain characterized by the following steps:—providing a support having a surface,—depositing on the surface one mono-layer of temporary particles,—depositing a coating on the temporary particles in such a way that the thickness of the coating is less than the particle diameter,—eliminating the temporary particles and thereby obtaining a porous coating, the pores of the coating corresponding to the spaces previously occupied by the temporary particles and at least a part of the pores communicating with the external environment,—applying a coating fixation step, characterized by the fact that it furthermore comprise a filling step where the pores are at least partially filled with a liquid or solid substance. The invention also concerns a coating and an object which can be obtained with this process.
