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
Liquid drop on a solid surface, solid - liquid - gas-phase at the intersection do gas - liquid interface tangent, this tangent with the solid-liquid boundary line between folders
Angle, shown in Figure 1. Under test, the contact angle of the solid surface with water called the water contact angle, the contact angle of oil called oil contact angle.
Note. The contact angle is one of the main indicators assessed double super sparse material.
3.2
Hydrophobic hydrophobicity
Surface water has a very low affinity and non-wetting.
3.3
Oleophobic oleophobicity
Surface has a very low affinity for oil and non-wetting.
3.4
Adhesion adhesiveforce
The degree of surface hydrophobicity and oleophobic properties. Materials exhibit adhesion droplets, called water adhesion; oil droplets exhibit
Adhesion force, known as the oil adhesion.
Note. Adhesion is another key indicators assessed double super sparse material.
3.5
Ultra-sparse dual nanomaterials super-hydrophobicitynanomaterials
Treated by nano-technology, nano-material having a surface structure, with hydrophobic and oleophobic properties, the water contact angle of not less than 150 °, the contact angle is not oil
Less than 120 °, and the aqueous adhesion of not more than 10μN, oil adhesion of not more than 10μN material called super AMPHIPHOBIC nanomaterials.
