3 Terms and Definitions

GB/T 19619 and defined by the following terms and definitions apply to this document. 3.1 The contact angle contactangle Gas gas, liquid and solid junction - liquid interface and solid - liquid interface angle between the tangent. Symbol denoted θ, in degrees (°). 3.2 Sessile drop method sessiledropmethod It is calculated using the detection method of the contact angle of a droplet measuring the measurement surface of the drop shape. 3.3 Static contact angle staticcontactangle Droplet volume constant contact angle of the sessile drop method at a specified time measurement. Symbol denoted θsta, in degrees (°). 3.4 Advancing contact angle advancingcontactangle Not with the droplet volume increases and changes in the contact angle of the liquid-solid interface to replace the gas-solid interface formed in the process. Symbol denoted θadv, units Degrees (°).

4 measuring principle

1, a liquid drop on a solid surface, solid - liquid - gas-phase junction for gas - liquid interface tangent, the tangent and the solid-liquid deposit It is the angle between the line between the contact angle. For a given system, the contact angle depends on the size of the three-phase interface (liquid/gas, solid/gas and liquid/solid) Room Interaction. ......
