报告题目：Assembly of Carbon Nanomaterials for Emerging Applications
Carbon nanomaterials have many extraordinaryproperties. However, they often lose their desired properties observed innanoscale when used as the building block of macroscopic systems. This talkcovers our research efforts on understanding and addressing this challenge in severalareas. First, we found the antibacterial activity of carbon nanomaterials iscorrelated with their metallicity, size and aggregation.Second,we used capillary columns and space-confined channels as hydrothermal reactorsto assemble graphene oxide sheets and carbon nanotubes into unique multiscalehierarchical structured hybrid fibers, which shows high volumetric capacitance.The hybrid carbon fibers were used to construct fiber supercapacitors. Thesedevices can cover a wide range of energy and power needs, and they demonstrategood potentials as energy storage solutions for wearable and implantabledevices.Third, graphene oxide sheets were used to modulateproperties of polymeric hollow fiber membranes for water treatment. Further,versatile carbon architectures were designed by intercalatingsurface-functionalized, small-diameter, multi-walled carbon nanotubes intoreduced graphene oxide sheets to create highly stable membranes with engineerednanochannels, demonstrating improved water permeability and enhanced membraneselectivity.
