논문 초록 (Abstract)
We report the synthesis ofgraphenes with tunable properties dueto the growth of needlelike iron oxide(IO) nanoparticles on their surfaces.The electrical conductivity, flexibility,and magnetic properties of graphenenanosheets (GNSs) could be tuned ondemand by fine controlling both thesurface coverage and the length of theIO nanoneedles. The degree of cover-age of the IO nanoparticles on the sur-face of the GNSs made it possible to control the resulting properties of theIO/GNSs on demand. As examples oftheir utility, paperlike materials weregenerated by simple filtration, and theresulting IO/GNS nanocompositesshowed extraordinary removal capacityand fast adsorption rates for AsVand CrVIions in water. Another possibleapplication is the preparation of multi-functional films equipped with conduc-tivity, flexibility, and magnetic proper-ties. The fabrication process is easy toscale up at a low cost. In addition, boththe colloidal solution and film forms ofthe resulting IO/GNSs were effectivefor removal of heavy metal ions, mean-ing this material could be utilized foractual industrial applications.
