Abstract

The invention provides a Pickering emulsion. The Pickering emulsion comprises an oil phase and a water phase, wherein the volume ratio of the oil phase is 4.2%-90%, Alg-beta-CD is dispersed in the water phase, and AzoC12 is dispersed in the oil phase. The invention further provides a super-amphiphilic host-guest alginate-based anisotropic structure soft substance prepared from the Pickering emulsion. A novel amphiphilic-controllable super-amphiphilic Alg-beta-CD / AzoC12 self-assembly is designed and prepared, has better interface adsorption performance and can be used for preparing a W / O / W emulsion with good stability by a phase inversion method. The amphipathy of the super-amphiphilic aggregate can be properly adjusted on the basis of host-guest action, an ideal and convenient strategy can be provided for phase separation behavior control of the host-guest multiphase emulsion, so that the structural diversity of the soft material is realized, and the Pickering emulsion has potential application value in colloidal materials.

Description

technical field [0001] The invention relates to a method for preparing a super-amphiphile host-guest alginate-based anisotropic soft material. Background technique [0002] Heterogeneous Pickering emulsions have great application potential in drug encapsulation, industrial production, and material science. In recent years, heterogeneous Pickering emulsions have been explored as ideal templates for interfacial self-assembly to achieve diverse morphologies of anisotropic structures. Due to the irreversible adsorption of interfacial stabilizers, colloidal nanoparticles-stabilized heterogeneous Pickering emulsions exhibit better stability, in sharp contrast to conventional surfactant-stabilized heterogeneous emulsions with different hydrophilic-hydrophobic balance (HLB). In addition, traditional multiphase emulsions not only require two emulsification steps, but also require a large amount of energy input to reduce the interfacial potential energy. In the formation mechanism o...
