Introduction of Surface water drop angle Angle Testing
Water drop angle test, also known as contact angle test.
Contact angle,refers to the tangent of the gas-liquid interface selected at the intersection of the gas,liquid and solid three phases,the angle θ between the tangent line and the solid-liquid boundary line on the edge of the liquid,as the measurement material Parameter for the degree of surface wetting.
The water contact angle test has become the main detection method for the hydrophobicity of semiconductor materials, glass, plastics and other materials.
