We studied the self-assembly processes and morphologies of tetrapod nanoparticle solutions using dissipative particle dynamics (DPD) simulations. Composite-shaped nanoparticles, such as a tetrapod model with an amphiphilic surface pattern, were also synthesised experimentally. We programmed nanoparticle self-assembly using the DPD results at various values of the hydrophobic ratio (HR) and arm length (AL). Considering these two parameters, we observed the self-assembly processes and morphologies in a tetrapod nanoparticle solution. As a result, it was found that the HR and AL of tetrapod nanoparticles were effective parameters for controlling their self-assembly processes or structures under equilibrium. In this study, we programmed the AL or HR parameters, and we report their influences on self-assembly. Our simulations offer a guide to controlling the morphologies of self-assembled tetrapod nanoparticles, which constitute novel systems that may find applications in nanofluidic devices.

具有两亲表面图案的四足动物纳米颗粒的程序化自组装：臂长和疏水比的影响†

我们使用耗散粒子动力学（DPD）模拟研究了四脚架纳米颗粒溶液的自组装过程和形貌。还通过实验合成了复合形状的纳米粒子，例如具有两亲表面图案的四足动物模型。我们使用疏水性比（HR）和臂长（AL）的各种值的DPD结果对纳米粒子的自组装进行编程。考虑到这两个参数，我们观察到了四脚架纳米颗粒溶液中的自组装过程和形貌。结果，发现四足体纳米颗粒的HR和AL是在平衡下控制其自组装过程或结构的有效参数。在这项研究中，我们对AL或HR参数进行了编程，并报告了它们对自组装的影响。
