主 题：contact angle hysteresis receding angle surface microstructure area fraction contact line ratio wetting
摘 要：Recent studies have shown that the triple-phase contact line has critical effect on the contact angle hysteresis of *** this study,patterned surfaces with various surface structures of different area fractions were prepared by electron etching on a silicon *** advancing angle,receding angle and hysteresis angle of these surfaces were *** experimental results showed that while the geometry of microstructure and contact line have a minor effect on the advancing angle,they have a significant effect on the receding angle and thus the hysteresis *** have shown that the effect of microstructure and the contact line can be described by a quantitative parameter termed the triple-phase line *** theoretical predictions were in good agreement with our experimental results.
