To integrate surface and interfacial properties and phenomena into the Hansen solubility parameter (HSP) framework, we propose an equation for estimating both surface tension/energy for liquids and solids as well as interfacial tension/energy. The contact angles of probe liquids on various polymers estimated using the proposed equation based on bulk HSPs (derived from bulk properties such as solubility or swelling, and not on surface properties) are compared with those measured using the sessile drop method. It is found that their correlations are sufficient for predicting wettability in practical use. All the respective tension and energy correlations are reasonably good, confirming the predictive power of the proposed equation for all values of liquid surface tension, solid surface energy, and interfacial tension. The unification of surface and interfacial properties and phenomena with HSPs (derived from bulk properties) enables us to estimate the surface properties from bulk properties and vice versa. The huge database of HSPs is now applicable to not only bulk phenomena but also surface and interfacial phenomena. Furthermore, complex processes or systems composed of multiple constituents and phases can be understood and designed using the modified HSP framework.
为了将表面和界面性质及现象整合到汉森溶解度参数（HSP）框架中，我们提出了一个用于估算液体和固体的表面张力/能量以及界面张力/能量的方程。将基于本体HSPs（由诸如溶解度或溶胀等本体性质而非表面性质推导得出）使用该方程估算的探针液体在各种聚合物上的接触角与使用静滴法测量的接触角进行比较。结果发现，它们之间的相关性足以在实际应用中预测润湿性。所有各自的张力和能量相关性都相当良好，证实了所提出方程对于液体表面张力、固体表面能和界面张力的所有值都具有预测能力。表面和界面性质及现象与（由本体性质推导得出的）HSPs的统一使我们能够从本体性质估算表面性质，反之亦然。现在，庞大的HSPs数据库不仅适用于本体现象，也适用于表面和界面现象。此外，使用改进的HSP框架可以理解和设计由多种成分和相组成的复杂过程或系统。
