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 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 it furthermore comprise a filling step where said 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.
