I think the combination of organic and inorganic materials can be termed as hybrid materials. Recently we have reported a functional hybrid coating material which has been prepared by the combination of polyurethane and POSS nanoparticle (Macromolecules 2018, 51, 4770−4781).
You are describing hybrid materials. However, the term „hybrid coating“ might be more process related... this would need the combination of ener sources / processes.
