Microstructural ordering of nanofibers in flow-directed assembly

摘要: Fabrication of highly ordered and dense nanofibers assemblies is key importance for high-performance multi-functional material device applications. In this work, we design an experimental approach in silico, where shear flow solvent evaporation are applied to tune the alignment, overlap nanofibers, density assemblies. Microscopic dynamics process probed by dissipative particle simulations, hydrodynamic thermal fluctuation effects fully modeled. We find that microstructural ordering assembled can be established within a specific range Peclet numbers rates, while properties their interaction crucial local stacking order. The underlying mechanisms elucidated considering competition between coupling fluctuation. Based on these understandings, practical channels nanofiber assembly with promising mechanical performance outlined.
