摘要	We reported the interactions of the gravitational sedimentation, interface shrinkage, and outward capillary flow in drying droplets. This coupling effect is the inference we draw from deposition patterns of both sessile and pendant droplets which contain articles of different sizes, evaporating on a patterned substrate. The deposition difference between sessile and pendant droplets containing microparticles indicated that gravitational sedimentation has a significant influence on the deposition morphology. The phase diagram shows that the particle deposition process can be divided into two stages: in the first stage, the competition between the interface shrinkage and the gravitational sedimentation determines whether the particles can be captured by the liquid air interface; in the second stage, the capillary flow takes the particles inside the droplet toward the edge. The deposition morphology is the result of competition and cooperation interactions of the free setting, interface shrinkage, and outward capillary flow.
