Preparation and properties of Janus nanoparticles at pickering emulsion interface

Abstract

Janus nanomaterials are characterized by their anisotropic structural properties, wherein two distinct chemical compositions or polarities coexist inside the same structure. These materials are typically observed at the nanoscale or micrometer level and are mostly synthesized through chemical modification or organized assembly facilitated by intermolecular interactions. The preparation process of Janus material is contingent upon the intricacy of its structural complexity. Various preparation methods have been devised to address important aspects such the composition of components, control over size and morphology, and localized alteration of functionality such as interface protection, phase separation, microfluidic control, self-assembly, among others. The Pickering emulsion templating method is widely recognized as a highly effective approach for the synthesis of Janus particles. On the other hand, the structural composition and straightforward fabrication of Janus nanoparticles play a crucial role in facilitating the interface catalysis of Pickering emulsions. The paper employed literature review and literature analysis as research methods to investigate the assembly of Janus nanoparticles at the Pickering emulsion interface. Additionally, the study aimed to examine the properties and potential uses of Janus particles across different domains. The utilization of Janus materials has demonstrated promising potential in several applications such as emulsification, encapsulation, catalysis, drug delivery, battery separators, and the creation of superstructure materials.
