Assembly of Carbon Nanomaterials for Emerging Applications
Prof. Yuan Chen*
School of Chemical and Bimolecular Engineering, The University of Sydney, Sydney, Australia
Carbon nanomaterials have many extraordinary properties. However, they often lose their desired properties observed in nanoscale when used as the building block of macroscopic systems. This talk covers our research efforts on understanding and addressing this challenge in several areas. First, we found the antibacterial activity of carbon nanomaterials is correlated with their metallicity, size and aggregation.1-4 Second, we used capillary columns and space-confined channels as hydrothermal reactors to assemble graphene oxide sheets and carbon nanotubes into unique multiscale hierarchical structured hybrid fibers, which shows high volumetric capacitance. The hybrid carbon fibers were used to construct fiber supercapacitors. These devices can cover a wide range of energy and power needs, and they demonstrate good potentials as energy storage solutions for wearable and implantable devices.5-8 Third, graphene oxide sheets were used to modulate properties of polymeric hollow fiber membranes for water treatment. Further, versatile carbon architectures were designed by intercalating surface-functionalized, small-diameter, multi-walled carbon nanotubes into reduced graphene oxide sheets to create highly stable membranes with engineered nanochannels, demonstrating improved water permeability and enhanced membrane selectivity.9-11
