Effect of Surface Wettability on the Sessile Droplet Evaporation

摘要：

　　In this study,crystallized Polycarbonate(PC)surfaces are fabricated by the immersion durations in liquid acetone.Droplet evaporation on the surfaces was studied using a contact angle meter at room temperature,and the evolution of contact angle,contact diameter,droplet volume and droplet height against evaporation time are analyzed.The results showed crystallized PC surfaces(CPCS)have hydrophobic.CCR mode is appeared in the most of evaporation period as sessile droplet evaporation occurred on the crystallized PC wafer surface.For untreated PC wafer surface(UPCS),sessile droplet evaporation showed three evaporation modes.The temporal variation of the droplet volume versus time makes a difference on the crystallized and untreated PC wafer surfaces.The droplet height decreased almost linearly with time for both surfaces.
