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.为简化基于范奥克斯-乔杜里-古德（van Oss-Chaudhury-Good）方程的表面能测角法测定，本数据集展示了如何利用包含三种完全表征液体（例如1-溴萘、甲酰胺与水）表面张力分量的电子表格，通过线性代数方法同时求解基底的三种表面能分量（即非极性分量、酸性分量与碱性分量）。随后可利用上述分量计算该基底的酸碱分量与总表面能。上述表面能分量共同构成五分量表面能图谱，可用于预测该基底与相互作用材料之间的界面性质。该基底可为任意固体或半固体材料，包括但不限于金属、陶瓷、玻璃、聚合物、塑料、凝胶、生物大分子，以及均匀平面生物表面。
