HYBRID MATERIALS AND COATINGS
In addition to sol-gel chemistry, other routes are developed at SPECIFIC POLYMERS to prepare hybrid formulations, such as the intimate mixing of inorganic fillers into polymeric resins or the functionalization of particles according to the “grafting-from” and “grafting-to” techniques.
We have thus addressed multiple subjects in functional coatings going from anti-corrosion coatings in extreme conditions, super-hydrophobic surfaces for self-cleaning, self-healing materials, to conductive or fire-proofing coatings. As an example, the development of a highly conductive paint for lightning protection is on-going. The objective is to find the best combination of metallic and carbon-based particles and polymeric matrices of different chemical natures, to create conductive channels with the lowest number of fillers, while showing excellent weatherability and mechanical properties.
A wide range of phosphorus flame retardants are available to meet the specific requirements of applications in various fields.

Phosphorus flame retardants that can be covalently linked to various polymeric matrices (epoxy, PU, sol-gel, acrylate) were also designed due to the need for fire-proof materials. These additives act mainly in the solid phase of burning polymeric materials and cause the polymer to char, thus inhibiting the pyrolysis process necessary to feed the flames.
