| 英文摘要 | Ordered arrays and structures of colloidal particles exhibit unique optical, electrical, chemical properties based on the shape, composition and arrangement of particles, which can be used for diverse applications including photonic crystal devices, chemical sensors, and printed electronics. We have put forward an ultrafast approach for the fabrication of ordered structures based on an injected colloidal droplet on the porous substrate. It has been demonstrated that the rapidly radial flow induced by capillary draining is responsible for the coffee ring, while both the oriented porous surface and the capillary forces assist for the self-assembly of colloidal particles into ordered structures. If the imbibition induced assembly (IIA) can be combined with 3d printing process, the complex shape and large area of ordered structure could be rapidly obtained.
