We are a team working on combining chemistry, chemical engineering, materials engineering, and experimental/theoretical analysis for development of coatings and bulk ceramics in a life-cycle analysis context.
Our research interests cover functional surfaces, with large effort into anti-icing and anti-fouling surfaces as well as bioactive surfacees, and the knowledge and experience needed to obtain the functionality. We have strong focus on the properties of the underlaying substrate and its surface chemistry. The coating compatibility to the substrate is important, and hence the final mechanical properties. The focus is both on micro and nano level. Including the focus on the materials and the life-cycle analysis has been more and more important to ensure sustainable surfaces.
We have significant activities on ceramic processing covering the whole range from powder production, dispersions, shaping and sintering. Current activities are directed towards 3D printing of both structural and functional materials as well as sintering studies aiming at optimal strength. Other activities include electrophoretic deposition and inkjet printing. Several of our research activities are in close collaboration with Norwegian core industry.
