Abstract
There is provided a method for treating a surface comprising heating the object and the object with a solution comprising a thermal initiator and a polymerizable molecule, wherein the polymerizable molecule reacts with the surface and forms a covalent bond and optionally a covalently bound polymer on the surface of the object. Metal ions are bound to the surface to make the surface possible for adding further metal later. Advantages include that complicated geometries can be coated, problems with oxygen inhibition of the initiator is reduced, and surface reaction to form covalent bonds is promoted compared to the bulk polymerization reaction.
