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...
