Structured Liquids:Design,Construction and Applications
Structured liquids are a new type of non-equilibrium soft materials constructed by the assembly and jamming of solid particles at the liquid/liquid interface,combining the structural stability of solids with the fluidity of liquids.However,the preparation of smart structured liquids and derived functional materials with precise structures is still challenging,due to the lacking of suitable building blocks and manufacturing methods.Our group has carried out a great deal of research work in this field,and has achieved a series of significant results in the development of new self-assembly mechanism at the interface,the preparation of new liquid/solid materials,and the construction of novel devices with advanced functions.In this review,we highlight a generalized strategy for the preparation of structured liquids by using the formation,assembly and jamming of nanoparticle surfactants,in which nanoparticle surfactants are generated by the co-assembly between nanoparticles and polymeric ligands at the liquid/liquid interface.We first introduce the self-assembly mechanism of solid particles at the liquid/liquid interface.Then we summarize the progress in the construction of structured liquids and derived materials.Finally,we provide an outlook of the opportunities and challenges in this field.
