标题： De-pinning of contact line of droplets on rough surfaces

摘要： 本研究报道了在DVD凹槽面涂覆的PDMS聚合物上，在醇类饱和蒸气下自组装液滴图案的形成。 与DVD无约束面形成的呼吸图进行比较。 使用了四种不同的环境，即甲醇、乙醇、2-丙醇和正丁醇进行分析。 观察到甲醇和乙醇蒸气下会发生图案形成，而2-丙醇和正丁醇则不会。 不同醇类导致图案形成差异是由于链长的变化以及醇中疏水基团的存在，如Traube定律所述。 在约束表面上图案的畸变归因于接触线的脱离。 显示英文摘要

摘要： The present study reports the formation of self-assembled droplet pattern on the PDMS polymer coated over grooved side of DVD under saturated vapours of alcohols. Comparison of the results with breath figures formed over unconstrained side of DVD is made. Four different environments namely methanol, ethanol, 2-propanol and n-butanol are used for the analysis. It is observed that the pattern formation occurs with methanol and ethanol vapours and not with 2-propanol and n-butanol. The difference is pattern formation with different alcohols is attributed to the variation in chain length and the presence of hydrophobic groups in alcohols, as given by Traube's rule. The distortion of patterns over constrained surface is attributed to the depinning of contact lines.
