The invention discloses a structured
liquid drop and a preparation method and application thereof, the structured
liquid drop comprises an interfacial film and a first solution, the first solution is placed in a cavity enclosed by the interfacial film, the structured
liquid drop is dispersed in a second solution, and the second solution and the first solution are immiscible; and when the structured liquid drop is extruded by external force smaller than a threshold value, the shape of the structured liquid drop is changed. According to the preparation method disclosed by the invention, the water-soluble star-shaped beta-
cyclodextrin polymer with a clear structure is taken as an
assembly element, no high-molecular ligand is needed, and the interface
assembly of the star-shaped beta-
cyclodextrin polymer is induced by directly utilizing the interaction between the star-shaped beta-
cyclodextrin polymer and the oil-phase
solvent; an
assembly body with excellent
mechanical strength is constructed on a water-oil interface in situ, and preparation of the structured liquid drops is realized by combining
external field action.
