1· 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.
