Abstract

Topology, the study of properties that are invariant under continuous transformations, in which the number of pores (genus) is a profound concept that determines a number of properties that have been verified in many microscopic systems, but have not been studied in macroscopic materials. Microgels are widely used materials, and based on microfluidics, regular, stable, and reproducible microgels can be prepared, but studies from the perspective of topological principles have not been reported. In this paper, a system based on a boric acid ester rapid cross‐linking strategy that can rapidly capture topological changes during the transient process of droplet‐to‐ring transition is proposed. The electrical dissipation properties associated with different transient topologies during the process are also investigated, demonstrating that the change of topological structures in macroscopic materials also affected their electrical properties, laying the foundation for the design of modulated macroscopic micro structured materials based on topology theory.
