Plasma surface functionalization

 surfatron-reactor Plasma is a dry technology intrinsically ecological and environment friendly. It can be used to modify surface properties (at room temperature!)
  • Chemical inertia and affinity
  • Biocompatibility
  • Adhesion
  • Cleanliness and sterility
  • Increase surface roughness
  • Modify surface chemical groups
  • Improve/taylor wettability
  • Surface polymerization

Several plasma technologies are available at our group:

  • Low pressure RF/MW plasma treatments
  • Low pressure atom source treatments
  • Atmospheric pressure dielectric barried discharge (DBD) treatments

Environmental Applications of Plasma Technology:
Plasma Assisted Catalysis Applied to Decontamination Processes

TOI-plasma_catalysis Up to very recently, plasma and catalysis have been considered as separated investigation fields. In the last years, especially in the field of noxious gas treatments, it has been found that synergetic effects can be obtained if heterogeneous catalysts are used in conjunction with plasma processes.
