This decoration filler is good for EMI shielding (Electromagnetic interference shielding) by electro-conductivity. Owing to their conductivity, people do many studies about decorating metals on carbon materials. But sometimes results are worse than the originals, because of too much modified carbon materials for decoration. Although excessive modification makes lots of positions to decorate metal or metal oxide, number of sp2 orbitals are decreased by modifications. Here, this study use amphiphile polymers to decorate metals on graphene for keeping sp2 orbital. For analyzing Ag decorated graphenes, use SEM(Scanning Electronic Microscopy), TGA(Thermogravimetric Analysis), XRD(X-ray Diffraction) and Raman Spectrometer. Electromagnetic Interference shielding performance is tested with Vector Network Analysis as the samples are 2mm thickness in 1GHz-20GHz. |
