Preface
As is known to all, nanomaterials science and engineering have become the world's research hotspots. When studying the surface modification of nanomaterials, the concept of wetting contact Angle is often involved.Contact Angle refers to the level of a solid plane drops of a droplet and solid on the surface of the solid - liquid - gas three-phase junction, the gas-liquid interface and the solid-liquid interface two tangent to clamp the liquid phase in the Angle.
The surface can be a measure of the breakdown of chemical bonds between molecules on the surface of the material.In the theory of solid physics, the surface atoms have more energy than the atoms inside the material, and therefore, according to the principle of the lowest energy, the atoms spontaneously tend to the interior rather than the surface.Another definition of surface energy is that the material's surface is more energy than the interior of the material.
The pull of the interaction of the boundary between the two adjacent parts of the liquid surface perpendicular to their unit length.The formation of surface tension is closely related to the special stress state of the molecules in the thin layer of the liquid surface.The existence of surface tension forms a series of special phenomena observed in daily life.

Instrument introduction
The instrument adopts the modern manufacturing technology, instrument adopts advanced special CCD digital camera, high resolution zoom microscope with times background and high brightness LED light source system, match 3 d sample sets, workbench can be up and down, left and right sides, front and rear direction.To achieve the micro - sampling and up and down, left and right precision movement.It also designed the telescopic rod structure table, which can adapt to the occasion of increasing the thickness of different user materials.The instrument frame can be adjusted according to the size of the style, and the scope of the instrument can be expanded.The software collocation correction function, the test results can be saved in the same report several times, can let the user better control the material data.The instrument is designed to be beautiful, easy to operate and meet the needs of users.Applicable to all kinds of industry determination of contact Angle users.
Requirements for improvement of quality control
Optical contact Angle measuring instrument: it is a simple, fast and sensitive method to measure the wettability of solid surface.The surface tension of the solid surface can be measured indirectly.The following is a comparison table of test methods:
| The test method | advantage | shortcoming |
| Optical contact Angle measuring instrument | 1. The water drop Angle can be quantifiable and definite 2. Uniformity measurement 3. Small error value |
Cost is a little higher |
| Surface test agent | The cost is low | The error is large, and the accuracy is affected after multiple tests |
| Atomic force microscope AFM | Extremely small measurements (atomic surface, nanostructure) | High cost, small image, slow speed, easy to damage the probe |
