1. Summary

contact angle(Contact angle) refers to the interaction between gas, liquid, and solidthree-phaseThe tangent line of the gas-liquid interface at the intersection point, which is located between the liquid side and the solid-liquid boundary lineincluded angleθ， Contact angle measurement is currently the main method for surface performance testing.

Optical contact angle measuring instrumentIt is based on the principle of optical imaging, and the equipment uses image contour analysis to measure the surface of the samplecontact angle、Wetting performance、Surface tension, forward and backward angles、Surface energyThe equipment adopts a fully automatic liquid inlet device with high cost-effectiveness, strong scalability, comprehensive functions, and can meet various conventional measurement needs. It has been widely used in many universities, colleges, and enterprises.
