我们利用耗散粒子动力学（DPD）模拟研究了三脚架纳米粒子溶液在纳米缝中的自组装形态。在本研究中，复合形状的纳米粒子，像一个平面的三脚架模型与两亲性的表面图案，也实验合成。使用DPD结果在不同的值的疏水比（HR）和臂长（AL），我们创建相图的三脚架纳米粒子的自组装形态。使用这两个参数中的每一个，我们在三脚架纳米颗粒溶液中观察到三种形态。此外，势能与温度的各种三脚架纳米粒子的解决方案进行了比较，为不同的自组装结构。我们的模拟提供了一个指导，以控制自组装的三脚架纳米粒子，这构成了新的系统，可能会发现在纳米流体设备中的应用形态。
We have studied the self-assembled morphologies of tripod nanoparticle solutions confined in nanoslits using dissipative particle dynamics (DPD) simulations. In the present study, composite-shaped nanoparticles, like a planar tripod model with an amphiphilic surface pattern, were also synthesized experimentally. Using the DPD results at various values of a hydrophobic ratio (HR) and arm length (AL), we create phase diagrams of the self-assembled morphologies of tripod nanoparticles. With each of the two parameters, we observe three morphologies in the tripod nanoparticle solution. Further, potential energy vs. temperature for various tripod nanoparticle solutions is compared for different self-assembled structures. Our simulations offer a guide to control the morphologies of self-assembled tripod nanoparticles, which constitute novel systems that may find applications in nanofluidic devices.
