用聚二甲基硅氧烷制备的,表面复制有微图形的"弹性印章"直接在聚乙烯,聚丙烯,聚苯乙烯和聚甲基丙烯酸甲酯等热塑性聚合物表面上进行热微模塑,无需复杂设备并可在普通实验室条件下,复制微图形,甚至在小试管外壁的曲面上或在用毛细管形成的微突起表面上也能制备出微曲面图形.讨论了不同聚合物对生成微图形的影响,认为结晶性聚合物以及在温度变化时有较大收缩率的聚合物在微模塑中难以获得清晰图形.无定形聚合物如聚苯乙烯和聚甲基丙烯酸甲酯等能够获得清晰的微结构.

Micro-patterns on curved surfaces were generated by molding on molten polymers with a cured polydimethylsiloxane elastomeric stamp. Microstructures were easily and repeatedly produced with four thermoplastics of polyethylene, polypropylene, polystyrene and poly(methyl methacrylate) on some curved surfaces, even on the surface with a raising high made by a capillary tube in the normal laboratory condition. It was found that distinct patterns were difficult to obtain for crystallization polymers and polymers with big shrinkage when temperatures change. Clear microstructures or patterns could be obtained by molding with amorphous polymers such as PS and PMMA.
