Faglige interesser

Jeg arbeider først og fremst med områdene overflater og polymerer, gjerne i kombinasjoner slik som plast- og gummioverflater og polymere nanopartikler, og studerer egenskaper slik som adhesjon, stabilitet, osv. Jeg har gjennom årene arbeidet med mange produkter og proseseser og jeg er interessert i mange ulike fenomener.

Problemet er ofte å begrense seg, men nedenfor har jeg satt opp de områdene jeg er mest interesserte i nå, og som jeg nå forsker på i større eller mindre grad.

  • Adhesjon
  • Automatiske måle- metoder for overflatespenning og kontaktvinkler
  • Tynne filmer av syntetiske og naturlige polymerer
  • Framstilling og bruk av nanopartikler
  • Syntese, karakterisering og egenskaper av overflateaktive og/eller assosierende polymerer
  • Kinetikk for adsorpsjon og faseovergang av overflateaktive stoffer ellom olje og vann
