摘要

In the article the analysis of the main methods of calculations of interfacial free energy and surface free energy (SEP) values of solids,in which contact angle measurements' results play a key role,has been presented.The importance of Young's equation and Berthelot's hypothesis as the scientific basis of these methods has been indicated.Various methods of calculations of interfacial free energy values for solid-liquid systems,including calculations of this energy on the basis of state equations or SEP divide to independent components,(especially for polymers) were discussed.The most important methods of calculations of SEP values for polymeric materials on this basis were characterized.The methods of calculations of contact angle values for porous materials,granulated products,powders or fibers on the basis of Washburn equation,what is a base for calculations of SEP of these materials,were presented.
