Abstract


 

Interfaces are becoming key to development in a range of areas, including development of nanomeaterials and nanocomposities, green corrosion protection systems, bisurfaces and biomaterials, anti-icing technologies, and aqueous lubrication technologies. This presentation will provide an overview of some activities at the Surface and Corrosion Science Division at the Royal Institute of Technologyin Stockholm. The presentation will introduce and discuss the following topics:


 

The quest for green corrosion protective coatings, where we have achived promising results with several different systems including i) UV-cured polymer films (≈ 10 µm thick) incorporating small amount of conducting polymer, ii) superhydrophobic coating layers, and iii) thin films (≈ 100 nm) of mussel adhesive polymers and ceria nanoparticles.


 

Nanomechanical properties of the interphase, i.e. the region next to a particle embedded in a polymer matrix. Such studies are performed using scanning probe methods and provide direct measurements of nanomechanical properties with a high spatial resolution.


 

Molecular lubrication synergies underlying the outstanding lubrication properties of synovial joints, and the development of biomimetic lubricants providing low friction and high load bearing capacity in aqueous media, where we have achieved results that are comparable to that found in synovial joints.

 

 

The surface chemical approach to anti-icing and de-icing surfaces, where modification of surface properties are utilized for achieving low ice adhesion. At present it seems that such approaches could provide benefit for relatively small surfaces as found in heat exchangers and windscreens.
