The present invention relates to a pickering emulsion composition using polyimide particles and a method for preparing the same. The pickering emulsion stabilized by the polyimide particles according to the present invention has a very stable dispersed phase and does not cause flocculation, creaming, coalescence and phase separation even after a long time, and has an advantage of being capable of forming both an oil-in-water type emulsion and a water-in-oil type emulsion. Further, the polyimide particles used in the present invention can be synthesized in a simple manner and have partial wettability without the surface treatment and pH control so that they can be easily used for the emulsion stabilization.

A system for increasing the extraction of an active ingredient includes a vacuum quick-dissolving tank, a mixer, a solid-liquid separator, and a homogenizer. The vacuum quick-dissolving tank receives a sample. The mixer is connected to the vacuum quick-dissolving tank, and provides an aqueous solvent to be mixed with the sample. Heating, cooling, stirring, and vacuuming in the vacuum quick-dissolving tank make the sample dissolve and emulsify repeatedly between the vacuum quick-dissolving tank and the mixer to produce a mixture, which is output by the vacuum quick-dissolving tank. The solid-liquid separator receives the mixture output from the vacuum quick-dissolving tank for solid-liquid separation, and outputs an isolated sample liquid. The homogenizer receives the sample liquid output from the solid-liquid separator, performs high-pressure homogenization to obtain an extract liquid containing an active ingredient, and outputs the extract liquid. The homogenizer can increase the content of the active ingredient in the extract liquid.

A method for preparing a stabilized assembly includes combining a first liquid phase including nanoparticles and a second, immiscible liquid phase, dissolving in the second phase a first end-functionalized polymer having a first molecular weight, and a second end-functionalized polymer having a second molecular weight, wherein the second molecular weight is greater than the first molecular weight, applying a shearing external deformation field to increase the surface area of the first phase to create a new interface, wherein the nanoparticle surfactants form a disordered, jammed assembly at the new interface, and releasing the shearing external deformation field. The polymer and the nanoparticles can interact at an interface through ligand interactions to form nanoparticle surfactants and upon releasing the external deformation field the jammed assembly at the new interface traps the first phase in a deformed state having the first liquid phase and the second liquid phase as interpenetrating domains.
