The calculation of the interfacial energy, γ_(sv), could help to develop a theory of blood compatibility. However, it is acknowledged that this approach is not free of problems. All calculations of the γ_(sv) use the YOUNG-DUPRE-equation. Both Young's contact angle approach and Dupre'...
The meaning of ANGLE OF CONTACT is the angle between the meniscus and the containing walls of a column of liquid measured from the vertical wall below the surface of the liquid to the position of the tangent to the meniscus at its point of contact with t
This paper presents a refined test method and analysis procedure customized to estimate bitumen surface energy using contact angles measured by the Wilhelmy plate. Results for five neat and three modified bitumen are presented and results are interpreted to study the relationships between contact-angle ...
Contact angles are commonly used as a relatively simple method of estimating the free energy at the surface of a biomaterial. A contact angle refers to the angle made between a solid/liquid/gas interface on a surface. One method of creating a three phase interface is by simply adding a drop...
A computerized method for the calculation of surface energy parameters from all five liquids used to obtain an approximate solution for disperse, acid and base components of surface free energy greatly facilitated this task. 展开 关键词: Contact angle Sessile drop method Spruce wood Surface free ...
6.3.2.4 Contact angle measurement Contact angle tests of the polymer nanocomposites are generally conducted to investigate the surface hydrophobicity. Evaluation of the interactions between fillers and the polymer matrix (interfacial energy difference) can usually be done by measuring the contact angles of...
