浓密地收拾行李并且命令 suprastructures 是展出宽广应用的 nanomaterials 的新类型。cetyltrimethylammonium 溴化物(CTAB ) 直接自己组装形成 suprastructures 的盖住的金 nanotriangles 被改变温度系统地调查并且倾斜在汇编进程使用的硅晶片的角度。在最佳的条件下面, nanotriangles 变成常规模式,维持他们的正直,并且形成 edge-to-edge,点对点,并且在几百方形的微米的一个区域以内形成订的 suprastructures 的面对面连接,完成整齐的高水平。在最佳的条件下面的 suprastructures 的形成能主要被归因于在多重温度依赖者因素之间的复杂平衡,包括原子散开率,溶剂蒸发率,自己组装率,和 nanoparticle 呆在湿媒介的时间。
Densely packed and ordered "suprastructures" are new types of nanomaterials exhibiting broad applications. The direct self-assembly of cetyltrimethylammonium bromide (CTAB)-capped gold nanotriangles to form "suprastructures" was systematically investigated by varying the temperature and tilt angle of the silicon wafer used in the assembly process. Under optimal conditions, nanotriangles form into regular patterns, maintain their integrity, and form edge-to-edge, point-to-point, and face-to-face connections to form ordered "suprastructures" within an area of hundreds of square microns, achieving a high level of regularity. The formation of the "suprastructures" under optimal conditions could be mainly attributed to the complex balance between multiple temperature-dependent factors, including the atom diffusion rate, solvent evaporation rate, self-assembly rate, and the time for which the nanoparticle stays in the wet medium.
