Theoretical Analysis of Meniscus Forces between Two Spherical Nanoparticles at Various Humidities

Abstract:

The meniscus force between nanoobjects with a mediated liquid bridge plays an important role in many applications due to scale effects. As an typical configuration, the meniscus force between two spherical nanoparticles at various humidities is studied theoretically. The numerical method and the usual approximation method of calculating the meniscus force at various humidities are compared firstly. It is found that the big error may occur at some conditions. The effects of relative humidity on the meniscus force between spherical nanoparticles are investigated. Besides, the influences of spherical radius, the distance between nanoparticles, contact angles of the liquid on the meniscus forces between spherical nanoparticles are studied. The simulation results are helpful to understand and control the adhesion force at nanoscales.
