摘要
以鲨鱼皮表面的盾甲鳞结构为模板,采用复型翻模法和电铸法,在高分子表面进行表面微结构的复制.利用光学显微镜对采用不同材质和复制方法制备的样品的表面进行了观察和对比分析.结果表明:以固体硅橡胶PDMS作翻模材料的复型翻模法是较佳的表面微复制方法.以PDMS翻模制备的聚氨酯仿鲨鱼皮作为电铸原型,所制备的金属模具具有清晰和完整的盾甲鳞沟槽结构和轮廓,容易脱模,是电铸法制备具有鲨鱼皮表面微结构的金属模具的较可行的方式.
Adopting the riblet structure of sharkskin as a templet, two ways of micro-replication, replicated moulding and electroforming, were used to replicate the microstructure on the surface of a polymer. The surface microstructure of the samples prepared with different polymer matrixes by means of different methods was observed and analyzed with an optical microscope. The results indicate that the replicated moulding using solid silicone rubber PDMS as a matrix for replicated mould is a relatively perfect method of surface micro-replication, and that the electroforming is a feasible way to prepare metal mould with the microstructure of sharkskin when the sharkskin-like polyurethane sample prepared with the PDMS mould is used as a prototype for electroforming, The metal mould prepared via an electroforming possesses clear and complete riblet structure and profiles of sharkskin, and demoulding can be easily carried out.
