A thermally stable 2D array of spheres and their morphology control become important for the fabrication of novel nanostructures. Here, a simple method is presented for fabrication of large-area and well-ordered arrays of carbonized polystyrene (PS) hollow spheres with a controlled (close-packed or non-close-packed hexagonal) morphology, prepared by combining the self-assembly of PS-grafted silica nanoparticles, etching, electron irradiation, and subsequent thermal annealing. Fine control in the 2D or 3D nanostructure of carbon materials can open up new opportunities for high-performance nanoscale applications that require an efficient fabrication method for preparation of the porous carbon array.
一种热稳定的球形二维阵列及其形态控制对于新型纳米结构的制造至关重要。在此，提出了一种简单的方法来制备大面积且有序排列的碳化聚苯乙烯（PS）空心球阵列，其具有可控的（密排或非密排六方）形态，该方法是通过将聚苯乙烯接枝二氧化硅纳米颗粒的自组装、蚀刻、电子辐照以及随后的热退火相结合来实现的。对碳材料二维或三维纳米结构的精细控制可为高性能纳米级应用开辟新机遇，这些应用需要一种高效的制造方法来制备多孔碳阵列。
