N2 - The results of statistical study of acid-base approach to the determination of the surface free energy are presented. Plasma enhanced chemical vapour deposition (PECVD) in low pressure RF discharge was used to prepare diamond-like carbon (DLC) coatings. The plasma deposited films were investigated by means of contact angle technique in order to determine their surface free energy. Drops of various liquids were set on the film surface and the drop profiles were snapped with CCD camera. The obtained contact angle data using several testing liquids were analyzed by three- liquid acid-base method and the results retrieved on the basis of different liquid triplets used were compared. A multiple regression method for a determination of the surface energy from more than three liquids is suggested and its outputs are compared with the results obtained by standard three liquid acid-base approach.
