论文摘要
我们研究了流体流体界面处的单个椭圆形Janus粒子的平衡取向和吸附过程。颗粒表面包括疏水或亲水性的同等大小的部分。我们提出了自由能模型，以预测平衡方向，并将理论预测与晶格玻尔兹曼模拟进行比较。我们发现流体界面的变形强烈影响Janus椭圆形的平衡方向。 Janus椭圆形的吸附过程可以导致不同的最终取向，由粒子纵横比和粒子湿度对比的相互作用确定。
We investigate the equilibrium orientation and adsorption process of a single, ellipsoidal Janus particle at a fluid-fluid interface. The particle surface comprises equally sized parts that are hydrophobic or hydrophilic. We present free energy models to predict the equilibrium orientation and compare the theoretical predictions with lattice Boltzmann simulations. We find that the deformation of the fluid interface strongly influences the equilibrium orientation of the Janus ellipsoid. The adsorption process of the Janus ellipsoid can lead to different final orientations determined by the interplay of particle aspect ratio and particle wettablity contrast.
