Product Description
1.PrefaceAs is known to all, the science and engineering of nanomaterials has become a worldwide research hotspot. When studying the surface modification of nanomaterials, the concept of wetting contact Angle is often involved. The so-called contact Angle refers to the Angle formed when the liquid phase is caught by the tangents of the gas-liquid interface and the solid-liquid interface at the solid-liquid-air three-phase junction point on the solid surface when a liquid drop is dropped on the horizontal plane of a solid.Surface energy is a measure of intermolecular chemical bond damage when creating a material surface. In solid physics theory, the surface atoms have more energy than the atoms inside matter, so, according to the energy minimum, the atoms automatically tend inside matter rather than the surface. Another definition of surface energy is the excess energy of the material surface with respect to the material. Tension of the interaction between any two adjacent parts of the liquid surface perpendicular to their unit length dividing line. The formation of the surface tension is closely related to the special stress state of the molecules inside the thin layer of the liquid surface. The presence of surface tension forms a series of special phenomena that can be observed in daily life. 2.Instrument application field- TFT-LCD panel industry: measurement of glass panel cleanliness and coating quality; front coating quality measurement of TFT printing circuit, color filter and ITO conductor film, etc
