This paper considers the correctness of the application of Good-van Oss theory (vOGT) to the calculation of acid-base components of solid surface free energies. Theory equations are written in a matrix form, and their application is analyzed particularly from a mathematical point of view. A calculation procedure similar to the approach used for other scales of acid-base strength is suggested to obtain in a straightforward manner the necessary material coefficients. The chemical consequences of these considerations are also discussed. The acceptability of current experimental literature data and the validity of the calculations obtained from them by the proposed method are considered, showing the origin of some inconsistencies in current results. Some general considerations regarding the difficulties commonly encountered in the application of vOGT are also discussed, and it is shown that they can be rationalized or eliminated with more acid solvents being included in the solvent set and the properties of the reference solvent being correctly chosen. The difficulties encountered in correctly expressing the acid properties of some polymers are closely examined. Finally, some indications are given of the future possible developments of vOGT.

本文探讨了古德-范奥斯特理论(vOGT)在计算固体表面自由能酸碱成分时应用的正确性。理论方程以矩阵形式书写,并特别从数学角度分析了它们的应用。建议采用一种类似于用于其他酸碱强度标度的方法的计算程序,以直接获得必要的材料系数。还讨论了这些考虑因素的化学后果。考虑了当前实验文献数据的可接受性以及通过所提出的方法从这些数据获得的计算的有效性,揭示了当前结果中一些不一致的根源。还讨论了关于vOGT应用中常见困难的一些一般性考虑,结果表明,通过在溶剂组中纳入更多酸性溶剂并正确选择参考溶剂的性质,可以使这些困难得到合理的解释或消除。仔细研究了在正确表达某些聚合物的酸性性质时遇到的困难。最后,给出了vOGT未来可能发展的一些迹象。版权所有1997年学术出版社。版权所有1997年学术出版社
