Product introduction

As we all know, nanomaterials science and engineering has become a global research hotspot. When studying the surface modification of nanomaterials, the concept of contact angle for wetting often comes up. The so-called contact angle refers to when a liquid droplet falls on a solid horizontal plane, at the three-phase solid-liquid-gas connection point on the solid surface, when the two tangents of the gas-liquid interface and the solid-liquid interface sandwich the liquid phase The formed corner.

Surface energy is a measure of the breaking of chemical bonds between molecules in creating the surface of a substance. In the theory of solid physics, atoms on the surface have more energy than atoms in the substance, so according to the principle of least energy,atoms spontaneously gravitate towards the interior of the substance rather than the surface. Another definition of surface energy is the excess energy on the surface of a material relative to the interior of the material. The tractive force acting together between two adjacent parts of the liquid surface perpendicular to the line of division of their unit length. The formation of surface tension is closely related to the special stress state of molecules in the thin layer of the liquid surface. The existence of surface tension constitutes a series of peculiar phenomena that can be observed in everyday life.
