Functional surfaces

Adding value through nanotech

Surfaces and interfaces play a critical role in numerous chemical and physical processes, often holding the key to exploiting the full potential of new materials and their applications in fields as diverse as energy harvesting and storage, space aeronautics, watchmaking, and bio- and med-tech.

Surface functionality is affected by both its morphology and chemical composition. That’s why we specialize in nano-structuration, surface modification, and interfacial engineering to transform the nature of surfaces to suit your needs. We develop advanced technologies, which tailor the mechanical, electrical, optical, or wetting properties and functionality of surfaces by modifying their structures and chemical composition, as well as the associated upscaling platforms.

Our work

Our solutions will help you perfect the characteristics of a wide range of surfaces and materials. Here are some of our competencies:

Formulation of functional materials

  • Formulating and incorporating novel nanomaterials into printable inks and functional thin films
  • Basing high-sensitivity sensors on nanostructured layers, such as mesoporous films or molecularly imprinted polymers

 Micro- and nano-structuration of surfaces

  • Nano-structuring based on nanosphere lithography, interference lithography, and polymer self-assembly
  • Creating cost-effective and scalable nano-structuration processes on both 2D and 3D surfaces
  • Applications include the production of silicon-based, nano-porous membranes, structural coloration, and nanostructured 3D steel mold inserts and foils

Surface and interface chemical functionalization

  • Developing vacuum deposition capabilities, with applications such as barrier nanolayers for miniaturized atomic clocks; hydrophilic layers for medical devices; optical filters to reduce water and energy consumption; and ultrathin layers to improve the thermal properties of battery separators
  • Providing high-value surface coatings using wet deposition techniques, including colored photovoltaic modules, metallic coatings for 3D-printed radiofrequency components and novel molecular layers for the metallization of heterojunction solar cells
  • Combining high-resolution printing and spraying technologies with electroless plating to produce decorative and conductive patterns
