Polymeric capsules
By forming small droplets of dispersed phase on a membrane and initiating polymer precursor polymerization, capsules with narrow size distribution and uniform burst strength are prepared, solving the problem of uneven capsule size and strength in the prior art. This achieves the stability and controlled release of beneficial agents, and improves the product's shelf life and efficiency.

AI Technical Summary
Existing technologies struggle to achieve stability and controlled release of active ingredients during encapsulation, especially in maintaining the integrity of active substances throughout the supply chain. Furthermore, uneven distribution of capsule size and rupture strength affects product shelf life and efficiency.
By forming small droplets of dispersed phase on the second side of the membrane and initiating polymer precursor polymerization in the continuous phase, a capsule with a polymer shell surrounding the core is formed. This controls the size distribution and rupture strength of the capsule, ensuring the stability and release control of the beneficial agent within the capsule.
This achieves a narrow size distribution and uniform burst strength in the capsules, ensuring the uniform release of beneficial agents in the formulated product, improving product stability and efficiency, reducing the use of non-functional materials, and lowering costs and environmental impact.
