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 said surface one mono-layer of temporary particles, —depositing a coating on said temporary particles in such a way that the thickness of said coating is less than the particle diameter, —eliminating said temporary particles and thereby obtaining a porous coating, the pores of said 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 said temporary particles are deposited on said surface in such a way that, after particle deposition, more than 50% of the temporary particles are in contact with a maximum of two adjacent particles and otherwise are separated by an empty space. The invention also concerns a coating and an object which can be obtained with this process.
