Abstract

The invention discloses a preparing device of a shell-core functional material, which comprises a microfluidics integrated chip, a microfluidics drive device and a shell-core functional material collector; the microfluidics integrated chip comprises an outer phase input passage, a middle phase input passage, an inner phase input passage, a double emulsion generating micro structure, and a functional material output passage, and further comprises a bionic splitting array, a dielectrophoresis tuning micro unit, a liquid membrane curing micro unit, a microsphere external surface functionalized micro unit and a functional filler loading and homogenizing micro unit, which are arranged between the double emulsion generating micro structure and the functional material output passage. The preparing device can fully use the space of the microfluidics integrated chip, enables the chip to be compactly and reasonably configured and realizes the aim of fast and efficiently preparing the high quality shell-core functional material, thus greatly improving the preparing efficiency of the functional material under the conditions of ensuring degree of sphericity, concentricity and size uniformity of double emulsion, and realizing scaled and continuous production with excellent controllability.

Description

technical field [0001] The invention relates to a device for preparing a core-shell functional material by using a microfluidic method, and belongs to the technical field of double-layer emulsion preparation. Background technique [0002] Double emulsion is a nested multiphase system in which the outer droplets of the dispersed phase wrap smaller inner droplets. The unique shell-core microstructure of the double emulsion can effectively isolate the contact between the inner droplets and the continuous phase, so it is called It is widely used in the preparation of functional materials such as micro-memory, micro-reactor, micro-separator and micro-structural unit. The current commonly used double emulsion preparation methods usually have problems such as complex process, low efficiency and serious waste of raw materials, and due to the lack of effective regulation of the fluids in the process, the obtained double emulsion is not high in sphericity and concentric. The degree i...
