Abstract
Two-dimensional (2D) particles can be confined to a fluid–fluid interface to create a rheologically-complex interface with dynamic particle–particle and particle–membrane interactions that are still poorly understood. There are dozens of bulk materials from which 2D particles can be made, including graphene, graphene oxide, hexagonal boron nitride, molybdenum disulfide, and MXenes, and there is interest in utilizing them because of the unique properties they have over their bulk counterparts. Increasing use of 2D materials in consumer products and novel materials science applications such as Pickering emulsions, composite foams, and films, adds urgency to improve our understanding of how the atomically thin nature and variable chemistry of 2D particles makes their dynamics and interfacial rheological properties at fluid–fluid interfaces different than spheroidal particles. This short review highlights key advances that have been made in understanding the dynamics of 2D particles at fluid–fluid interfaces, including in interfacial rheology and particle–particle dynamics, and it includes discussion on important future research directions.
期刊介绍:
Current Opinion in Colloid and Interface Science (COCIS) is an international journal that focuses on the molecular and nanoscopic aspects of colloidal systems and interfaces in various scientific and technological fields. These include materials science, biologically-relevant systems, energy and environmental technologies, and industrial applications.
Unlike primary journals, COCIS primarily serves as a guide for researchers, helping them navigate through the vast landscape of recently published literature. It critically analyzes the state of the art, identifies bottlenecks and unsolved issues, and proposes future developments.
Moreover, COCIS emphasizes certain areas and papers that are considered particularly interesting and significant by the Editors and Section Editors. Its goal is to provide valuable insights and updates to the research community in these specialized areas.
