Nanomaterials over their parents
Performance Testing Methods
1 Scope
This standard specifies the terms and definitions of nanomaterials over their parents performance testing method, principle of the method, apparatus and reagents, sample preparation, detection
Conditions, test procedures and results evaluation, test reports.
This standard applies to detect nano-technology treatment, consisting of uniform, smooth, non-deformation (in the vertical component of the surface tension of the liquid
Under) and the performance of each super-parents to a solid surface with isotropic.
This standard does not apply to the measured liquid capable of absorbing material.

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. Adhesion is the main indicator assessment over parent material.
3.2
Hydrophilic hydrophilic
Performance has affinity for water, wettability. Surface contact angle with water of 90 ° or less hydrophilic.
3.3
Lipophilic oileophilic
The performance of oil has an affinity, wettability. The contact angle of the surface with the oil of less than or equal to 90 ° is lipophilic.
3.4
Super parents nanomaterials superamphiphilicnanomaterials
Nano-technology process, the surface having a nanostructure and hydrophilic lipophilic, water contact angle is less than or equal to 5 °, the contact angle of less than oil
Or equal to 5 ° in the material.
Principle 4
4.1 contact angle was used to characterize the extent of the wetting liquid to solid. In degrees, between 0 ° ~ 180 °. For a given system, then
Antennae are specific, depending on the interaction of the three-phase interface (liquid/gas, solid/gas and liquid/solid) between.
