TECHNICAL DESCRIPTION
Inventeurs
Patrick KEKICHEFF
Maryline CLAUZEL
This invention describes a process to coat a substrate by a polymer film, stable in humid
environment or when immersed in an aqueous solution. This universal process is
applicable to any kind of polymer (natural or synthetic, reticulated, branched, star-shaped,
copolymers, non-charged polymers or polyelectrolytes, fluoropolymers...) and any
substrate (metallic, mineral, organic, ceramics, inorganic and organic composites) of any
shape (flat, polyhedra, platelets, wafers, rings, curved and saddle-shaped, hollow tubes,
rods, and cylinders) with any kind of interface (smooth, rough, porous, amorphous or
crystalline, regular or irregular structures).

The process allows to obtain stable thin films adhering to the substrate even in a humid
atmosphere or when immersed in an aqueous solution in a static or in a flow of the
solvent. In addtion coating can be made whatever the topology of the surface is. As the
process does not modify the chemistry of the material, the functionality of the coatedpolymer film can be addressed and kept. The process can coat either the whole substrate
surface or can build patterns of spatially and structural controlled patches with different
physicochemical or/and functional properties as found in offset printing and lab-on-achips.
INDUSTRIAL APPLICATIONS
This technique can be used in numerous domains such as anti corrosion coating,
painting, bactericidal treatment, optical systems, electronics, solar energy, surface
modification of polymer, multilayer polyelectrolyte systems, adhesion, bonding, offset
printing, Lab-on-a-chip, chemical sensor manufacturing.
