英文摘要	Hypothesis: Self-assembly of colloidal particles enables the versatile fabrication of highly ordered struc-tures and materials for optical, sensing, and other applications. Nevertheless, many traditional assembly processes are inefficient, because there exists an inevitable contradiction between time efficiency and crystalline quality. In this work, we introduce an ultrafast, robust, and scalable approach of imbibition-induced assembly. We assume that the instantaneous solvent imbibition induced by the nanoporous media could direct ultrafast self-assembly of colloidal particles into ordered structures. Experiments: Self-assembly of colloidal particles from a droplet on a nanoporous substrate was firstly observed and investigated. A phase diagram of the thickness of the colloidal crystal as a function of the printing speed and the particle volume fraction was presented through systematic experiments.Findings: The nanoporous substrate can induce strong capillary flow that will direct the rapid self-assembly of particles into colloidal crystals. The imbibition-induced assembly was spatially and tempo-rally combined with the meniscus-guided printing approach, and the printing speed can be improved by two orders of magnitude than the traditional evaporative assembly methods. We finally demonstrate an effective and ultrafast approach for assembling colloidal particles into photonic crystals with control-lable sizes and shapes on the macroscale.(c) 2022 Elsevier Inc.
