The morphology and wetting stability of nanofilms formed by A_yB_yC_z miktoarm star terpolymers were explored by many-body dissipative particle dynamics. The length ratio of C- to A-arm (w = z/y) ranges from 0.25 to 5. On nonselective substrates, the nanofilm displays morphology as the lamella at w < 0.5, various Archimedean tilings at 0.5 ≤ w < 3, and the alternating lamella at w = 3. The nanofilm becomes unstable at w = 5. While our findings of Archimedean tiling patterns [6.6.6], [8.8.4], and [12.6.4] are consistent with thin film experiments, [8.6.4; 8.6.6] and [10.6.4; 8.6.4] have not been reported. The wetting stability was determined by the final fates of thin films subject to disturbances, including (i) nucleation and growth, (ii) self-healing, and (iii) stable hole. The stability follows descending order: [6.6.6] > [8.6.4; 8.6.6] > [10.6.4; 8.6.4] > [8.8.4] > [12.6.4] > alternating lamella > lamella > alternating cylinder. On selective substrates with weaker or stronger attraction with C-arms, the defects formed by C-arms prevail for the former but the lamella morphology dominates for the latter.

ABC Miktoarm星型三元共聚物纳米膜的形貌和润湿稳定性

通过多体耗散粒子动力学研究了由A _y B _y C _z miktoarm星型三元共聚物形成的纳米膜的形貌和湿润稳定性。C-至A-臂的长度比（瓦特= ž / Ý）范围为0.25至5.在非选择性底物，所述纳米膜显示形态学的薄片在瓦特在0.5 <0.5，各种阿基米德拼接≤瓦特<3，和w = 3时的交替层。纳米膜在w处变得不稳定= 5.虽然我们对Archimedean拼贴模式的发现[6.6.6]，[8.8.4]和[12.6.4]与薄膜实验一致，[8.6.4; 8.6.6]和[10.6.4; 8.6.4]尚未报告。润湿稳定性取决于受干扰（包括（i）成核和生长，（ii）自愈和（iii）稳定孔）的薄膜的最终命运。稳定性按降序排列：[6.6.6]> [8.6.4; 8.6.6]> [10.6.4; 8.6.4]> [8.8.4]> [12.6.4]>交替的薄片>薄片>交替的圆柱体。在选择性或弱于C臂吸引力的基板上，C臂形成的缺陷在前者中占优势，但薄片形态在后者中占主导地位。
