This paper reports a description of the theory of contact angle measurement and its use for the determination of surface energy of solids. The main objective of the work is to present a convenient approach to explain wetting phenomenon using contact angle theory. A brief review of Young’s equation and Young- Dupre equation is also presented followed by an extended Fowke’s equation widely used for the calculation of surface energy of solids. The two liquid model has been applied to determine the surface energy of polycarbonate and low density polyethylene.Key words: Contact angle; Surface energy; Surface characterization; Wettability; Young’s equation; Fowke’s modelThe Himalayan Physics Vol.2, No.2, May, 2011Page:1-4Uploaded Date: 31 July, 2011

The Right

High quality of the soldering process can be achieved with the right choice of the necessary soldering materials. Since wetting determines the further nature of the connection between the solder and the main soldering material, the contact angle  measurement  is the basis for quality control of soldering materials, provided that the basic requirements of the technological process. The determination of the contact angle value is carried out by the indirect method of the sessile drop, by measuring the basic parameters of the drop using infrared transducer. A smaller value of the contact angle corresponds to a better interaction of materials, and hence a better electrical contact

Microscopy Images

ZnO films with well-aligned hierarchical structures have been successfully synthesized at moderate temperatures using a simple catalyst-free hydrothermal process. The synthesized ZnO films are found to be single-phase, with a hexagonal wurtzite-type structure. Scanning electron microscopy images show that the well-aligned hierarchical structures are assembled with interlaced parallel sheets grown on the (400) silica surface. The water contact angle measurement indicates that the water on the films has a contact angle of about 156.3°. This clearly demonstrates that the ZnO films synthesized by this simple method have superhydrophobic properties and may be important for applications in self-cleaning surfaces, biology, and so on.
