Abstract:
Micromolding in capillaries of a micro-square array was carried out for polystyrene solution in acetone by means of swollen polydimethylsiloxane (PDMS) elastomeric stamp. The resulting micro-cubic poles were isolated and separable when the added amount of the polystyrene solution was small. Some special distorting micro-patterns in the micro-square array were observed because of shrinkage resulting from the varying evaporation rate of solvent at different places.
Key words:  Micromolding in capillaries, Swelling, Polydimethylsiloxane, Elastomeric stamp

摘要:
用溶胀后的聚二甲基硅氧烷弹性印章进行毛细微模塑,得到了 聚苯乙烯丙酮溶液的微四方点阵图案. 较少的PS溶液滴加量会造成孤 立不相连的微点阵图形. 同时还获得了由于在收缩过程中各部分溶剂 挥发速度不一造成的特殊的微点阵图案.
