Functional Composite Polymer Nanostructures and their Applications

Guofang Chen, St. John’s College of Liberal Arts and Sciences, Department of Chemistry

One-dimensional (1D) composite organic nanostructure materials, such as hybrid nanotubes, nanoparticles, nanorods, and nanograss, have attracted increasing interest in the thriving field of nanoscience and nanotechnology, because of their unique photonic, electronic, magnetic and biological properties. Integration of the advantages of low cost fabrication and ease in functionalization for organic nanomaterials and high efficiency of electron transportation, fluorescence and catalysis for inorganic nanomaterials, is able to generate composite materials with new structures, properties and functions with a lot of potential applications in biomedicine, new energy resources, sensors, and so on.
