Integral incline optical contact Angle measuring instrument

preface 

As we all know, the science and engineering of nanomaterials has become a worldwide research hotspot. The concept of wetting contact Angle is often involved in the research of surface modification of nanomaterials. The so-called contact Angle refers to the Angle formed when the two tangents of the gas-liquid interface and the solid-liquid interface clamp the liquid phase in the solid-liquid three-phase junction point on the solid surface, drop by drop on a solid horizontal plane.
