摘要
采用微电铸技术对生物表面形貌进行直接复制以成形出与生物原型形貌相接近的仿生表面,是生物复制成形技术由高聚物成形向金属沉积成形扩展的新途径。以鲨鱼皮为生物模板,针对其表皮微形貌结构特征,通过倾斜溅射方式先在其鳞片表面沉积导电层,进而采用正负间断脉冲电流对鲨鱼皮生物模板进行微电铸复制,成形出鲨鱼皮微电铸模板及仿鲨鱼表面。复制精度分析结果表明,采用微电铸生物复制成形工艺可以实现对鲨鱼皮外端沟槽微形貌的高逼真复制,证明该工艺可以应用于微尺度、复杂生物表面形貌的直接复制。
Direct replication of biological surface morphology using micro-electroforming method to form biomimetic surfaces with relatively vivid morphology is a new process extension from polymer forming to metal deposition forming of the bio-replicated forming technology.Taking shark skins as the replication templates,the conducting layer was deposited on the shark scales with the inclined magnetron sputtering process according to the structural characteristics of shark skins.Then the micro-electroforming process adopting the pulse-reverse currents was conducted.Finally the shark skin micro-electroforming template and the biomimetic shark skin were obtained.The preliminary analysis on replication precision indicated that the micro-electroforming method could be used to replicate the outward morphology of the shark skins with good precision,which validated the application of the bio-replicated forming technology in the direct replication of the complex and microscale biological surface morphology.
