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
- 《Energy & Fuels》 被引量: 72发表: 1994年 Surface tension of bitumen from contact angle measurements on films of bitumen Advancing contact angles, theta/sub A/, of water and glycerol were measured on films of bitumen. The bitumen was obtained by extracting different raw oil s... EI ...
Surface tension 1. Introduction Liquid behavior on porous substrates is determined simultaneously by spreading on the substrate’s surface and penetration into the bulk [1], [2]. A parameter affected by both, fluid and substrate, is the contact angle Θ of a liquid drop applied to the substrat...
Contact angle hysteresis may be observed due to the change in solid surface energy because of absorption of water or liquid [35]. In determining the surface hydrophobicity, reporting the contact angle hysteresis is important as contact angle. According to Eq. (12.1), the force required to start...

The contact angle depends upon the medium above the free surface of the liquid, and the nature of the liquid and solid in contact. It is independent of the inclination of solid to the liquid surface. It changes with surface tension and hence with thetemperatureand purity of the liquid. ...
Combining the Young and the Dupré equations, the computed results of surface tension together with contact angle data have been used to calculate the ... R Novakovic,E Ricci,ML Muolo,... - 《Intermetallics》 被引量: 59发表: 2003年 Correlation between interfacial free energy and albumin adso...
Surface free energy variations in Langmuir-Blodgett Multilayers: Contact angle measurementsIRREVERSIBLE PROCESSESMEMBRANE SYSTEMSNONISOTHERMAL PHENOMENAStatic contact angles have been measured during deposition of 22-tricosenoic acid on to hydrophobically treated silicon and the angles of immersion and emersion ...
4.4 Contact angle values Contact angle measurement provides information on the surface characteristics of films such as wettability, surface charge and tension, hydrophilicity, and interaction energy (Ismail, Islam, Khorshidi, Tehrani-Bagha, & Sadrzadeh, 2021). The contact angle is the angle between...
