Calculating the five-component surface energy profile from contact angles (goniometry)

With a purpose to simplify goniometric determination of surface energies via the van Oss-Chaudhury-Good equation, this dataset illustrates the ability to use a spreadsheet containing the surface tension components of three fully characterized liquids (e.g., 1-bromonaphthalene, formamide, and water) to linear algebraically and simultaneously solve for three surface energy components of a substrate (e.g., nonpolar, acid, and base components). The aforementioned components are then used to determine the substrate's acid-base component and the overall surface energy. Together the surface energy components provide a five-component surface energy profile that can enable the prediction of the interfacial properties of the substrate with an interacting material. The substrate could be any solid or semi-solid such as, but not limited to, metal, ceramic, glass, polymer, plastic, gel, biomacromolecule, or uniform, planar biologic surface.
