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.

三脚架纳米颗粒溶液的自组装形态：臂长和疏水比的影响†

我们已经研究了使用耗散粒子动力学（DPD）模拟将三脚架纳米粒子溶液的自组装形态限制在纳米缝隙中。在本研究中，还通过实验合成了复合形状的纳米颗粒，如具有两亲表面图案的平面三脚架模型。使用疏水性比（HR）和臂长（AL）的各种值下的DPD结果，我们创建了三脚架纳米颗粒自组装形态的相图。使用这两个参数中的每一个，我们都可以在三脚架纳米颗粒溶液中观察到三种形态。此外，势能与比较了各种三脚架纳米颗粒溶液在不同自组装结构下的温度。我们的模拟为控制自组装三脚架纳米颗粒的形态提供了指南，纳米颗粒构成了可以在纳米流体设备中找到应用的新颖系统。
