Embodiment 1

[0048] Adopt the sodium lauryl sulfate aqueous solution of 2% concentration as continuous phase fluid, adopt the tripropylene glycol diacrylate solution containing the photoinitiator 1-hydroxycyclohexyl phenyl ketone of 4% concentration as the fluid of microcapsule layer shell, The silicone oil solution containing 1% sorbitan fatty acid ester is used as the active material fluid that needs to be wrapped in the microcapsules, and the double microemulsion template is generated through the emulsion template generation component, and the microfluidic technology can continuously produce the double microemulsion template with good uniformity. Microemulsion templates such as Image 6 , Figure 7 . The double microemulsion template produces stable deformation in the stable shear flow field formed by the micro-shear bands. By adopting different shear strengths, double emulsions with different degrees of deformation can be precisely obtained, such as Figure 8 The four forms of a / b / c...

Abstract

The invention discloses a specially shaping device, a preparation device and a preparation method of multi-layer microcapsules. The specially shaping device of the special-shaped multi-layer microcapsules comprises a fluid box with a feeding port and is characterized in that two parallel shear belts are arranged in the fluid box, a specially shaping channel is arranged between the two parallel shear belts, and a fluid in the specially shaping channel forms a shear flow field for specially shaping the multi-layer microcapsules under the action of the shear belts in two different moving directions; the feeding port is located at the front end of an inlet of the specially shaping channel. Compared with the prior art, the device is simple in structure and high in controllability, and a novel method is provided for efficiently preparing the special-shaped multi-layer microcapsules.

Description

technical field [0001] The invention belongs to the field of microcapsules, and in particular relates to a multi-layer microcapsule with different shapes based on multiple emulsion templates and a preparation method and device thereof. Background technique [0002] Microcapsules are widely used in food, agriculture, medicine, chemical industry and other industries. The shell of microcapsules can isolate the active substances or toxic substances in the core of the microcapsules from the external environment and play an effective role in protection. The multi-layer shell microcapsules have higher flexibility, can better adapt to changes in the external environment, and are conducive to the release of active substances in the core under various stimuli. Among them, non-spherical special-shaped microcapsules are of great value in the directional release of drugs and the preparation of functional materials due to the anisotropy brought about by their special structures.
