具有多室结构的微胶囊在智能药物输运、微反应器、复杂传感器等方面具有重要的应用前景.提出了一种新颖的多流体复合电喷技术,可一步实现多室结构微胶囊的制备.该胶囊内部各室间有内壁相隔,每一个内室可独立的封装不同组分,各组分间互不接触.将一定数目的较细的内管插于较粗的外管组装了具有分级结构的复合喷头,这种独特的结构可以使电喷过程中壳材料形成对核材料的有效并且独立的包覆,从而导致了多组分同时包覆的多室结构微胶囊的制备.通过对复合喷头结构的设计可实现对腔室的数目以及相应的封装组分的数目的控制,并且可方便地扩展到其他功能材料的制备.该法制备的微胶囊不仅可以扩展单一胶囊的功能,而且其独特的多室结构可对被封装的核材料进行保护,尤其适用于活性材料如环境敏感性材料及反应性材料的同时包覆,将在多组分药物输运、微反应器等领域具有潜在的应用前景.
The microcapsules with multi-chamber structure have important application prospects in the fields of intelligent drug transport, microreactor, complex sensor, etc. A novel multi-fluid composite electrospray technology is proposed to realize the preparation of multi-chamber microcapsules in one step The inner chamber of the capsule is separated by the inner wall, each inner chamber can independently encapsulate different components, and the components do not contact with each other. A certain number of smaller inner tubes are inserted into the thick outer tube, This unique structure allows the shell material to form an effective and independent coating of the core material during the EFI process, resulting in the preparation of multi-component, multi-chamber microcapsules coated simultaneously The design of the composite nozzle structure can realize the control of the number of chambers and the corresponding number of packaging components and can be conveniently extended to the preparation of other functional materials.The microcapsules prepared by the method not only can expand the function of a single capsule, And its unique multi-chamber structure can be encapsulated nuclear material protection, especially for active materials such as environmentally sensitive materials and reactive materials coated at the same time, the multi-component Transport thereof, microreactors have potential applications.
