Overview

Portable contact angle measuring instrument: When a droplet reaches equilibrium on the surface of a solid, the angle between the gas-liquid interface and the liquid-solid interface at the junction of gas, liquid, and solid phases is called the contact angle. The contact angle is the main means to characterize the surface wettability of materials. The contact angle of hydrophilic surfaces is less than 60 degrees, the contact angle of hydrophobic surfaces is greater than 60 degrees but less than 120 degrees, and the contact angle of superhydrophilic surfaces is greater than 120 degrees.
