摘要

Abstract

Study of stable liquid crystal (LC) microdroplets is of great significance for LC dynamics in confined space or at topological surface. However

the fabrication of LC microdroplets with diverse shape without ionic gelation agents still remains challenging due to the fluid instability. Here

we utilize the microfluidic technology to prepare graphene oxide (GO) LC microdroplets with various morphologies based on the anomalous rheological property of GO aqueous dispersion. Different from LC of one-dimensional polymer

LC containing two-dimensional GO sheets exhibits considerable viscoelasticity and weak extensibility

resulting from the planar molecular conformation and the absence of intermolecular entanglements. The low extensibility ensures that GO aqueous suspension is discretized into monodispersed microdroplets rather than thin thread in the microfluidic channels. The large viscoelasticity and ultra-long relaxation time of GO LC enable the diverse stable morphologies of microdroplets. The droplet morphology is well controlled from sphere to teardrop by modulating the competition between GO viscoelasticity and interfacial tension. The two-dimensional GO LC featuring unique rheological property provides a novel system for the microfluidic field

and corresponding topological stability enriches the LC dynamics and opens a new pathway for designing graphene-based materials.
