The evaporating process of single polystyrene/xylene droplet on a substrate was experimentally studied. The effects of the initial polystyrene concentration (0-3.0 wt.%) and the initial droplet volume (pico litter and micro litter) were examined. Xylene droplet during evaporation was not so affected by the droplet volume, and the shape is nearly circle. However, that for polystyrene/xylene solution was affected both by the polystyrene fraction and the initial volume. The receding speed is apparently heterogeneous for the micro-litter droplet while that is nearly homogeneous for the pico-litter droplets.
