Patterning in the intensively evaporated polymer solutions based on polystyrene and poor solvent (acetone) was investigated. SEM and AFM studies demonstrated that annular elements of the surface topography are formed in this case, in contrast to the honeycomb patterns obtained under the evaporation of the good solvent (chloroform). The authors suggest that the theory of viscous dewetting developed by de Gennes explains the phenomenon satisfactorily.
研究了基于聚苯乙烯和不良溶剂(丙酮)的强烈蒸发聚合物溶液中的图案化现象。扫描电子显微镜(SEM)和原子力显微镜(AFM)研究表明,与在良溶剂(氯仿)蒸发下获得的蜂窝状图案不同,在这种情况下会形成表面形貌的环形元素。作者认为,德热纳提出的粘性去湿理论能够令人满意地解释这一现象。
