This work reports an efficient method to fabricate hexagonally patterned metal nanodot arrays at the sub-100-nm scale, which is based on contact printing via novel nanometer-scaled stamps. Vertically aligned carbon nanoposts, supported by hexagonally ordered nanochannels of anodic aluminum oxide templates, are employed as the stamping platform to directly transfer controlled metal nanodot arrays. Using the fabrication platform, a number of patterned metal nanodot arrays made of Au, Cu, Ni, Ag, Pt, Al, and Ti can be contact-printed over large substrate areas in ambient conditions. The size, density, and interdistance of the printed nanodots are controllable with a tight correspondence to the mother stamp geometries, which can be precisely tuned by modifying the pore dimensions of the alumina matrixes. An advanced example of contact printing of metal nanoparticles is successfully demonstrated by the controlled formation of nanodot arrays in a specific area.
这项工作报道了一种在亚 100nm 尺度下制造六方图案金属纳米点阵列的有效方法，该方法基于通过新型纳米级印章进行接触印刷。垂直排列的碳纳米柱，由阳极氧化铝模板的六边形有序纳米通道支撑，用作压印平台，以直接转移受控的金属纳米点阵列。使用制造平台，可以在环境条件下在大面积衬底上进行由 Au、Cu、Ni、Ag、Pt、Al 和 Ti 制成的多种图案化金属纳米点阵列的接触印刷。印刷纳米点的尺寸、密度和间隔距离可以与母版几何形状紧密对应进行控制，通过修改氧化铝基质的孔径可以精确调整。通过在特定区域中控制纳米点阵列的形成，成功地展示了金属纳米粒子接触印刷的一个高级示例。
