Fig. 2From: Evaluation of Protein Adsorption on Atmospheric Plasma Deposited Coatings Exhibiting Superhydrophilic to Superhydrophobic PropertiesPolar and dispersive contributions to surface free energy measurements on each test substrate. Polar components are assumed to be the sum of hydrogen, inductive and acid–base interactions and dispersive components the sum of Van der Waals interactive forcesBack to article page
