Chemical modification of diamond films using photolysis of perfluoroazooctane

摘要

Photolysis of perfluoroazooctane with diamond films led the chemical modification of the surface to introduce perfluorooctyl functional group,confirming by means of FT-IR,XPS,Raman and TOF-SIMS measurements.The diamond films modified with fluorine moiety showed improvement of reduction of surface energy evaluated by contact angle 118 deg to water,compared with pristine diamond film.
