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.
