Overview

Brief description: The colloidal interface contact angle tester can record droplet images and automatically analyze droplet shapes. The shape of a droplet is a function of the surface tension, gravity, density and humidity differences of different liquid samples, as well as the environmental medium. On solid surfaces, the shape and contact angle of droplets also depend on the properties of the solid, such as surface free energy and morphology. Analyze the obtained image using droplet contour fitting method, and measure the contact angle and surface tension. The surface free energy of materials can be calculated by conducting contact angle tests using several liquids with known surface tension.

The definition of droplet angle is the angle between the gas-liquid interface and the solid-liquid interface at the intersection of solid, liquid, and gasColloidal interface contact angle tester

Angle, droplet angle is a scale that displays the humidity of a solid surface, measured using most solid droplets. A low contact angle indicates a high humidity (hydrophilic) surface that is easy to adhere to. High contact water droplet angle indicates that the surface exhibits hydrophobicity, heavy organic pollution, or poor surface adhesion. The contact angle of a liquid in contact with a flat solid surface is determined by measuring the endpoint of the water droplet curve at the liquid solid gas junction and the contact point of the solid surface to analyze surface cleanliness. The contact angle is a scale that displays the humidity of the solid surface, and is measured using most solid droplets. A low contact angle indicates high humidity (hydrophilicity, hydrophobicity) and low surface energy.
