| Summary: | 碩士 === 國立臺北科技大學 === 有機高分子研究所 === 100 === The method of ball-milling and oxidation were applied in this study to produce small-sized particle graphene, then the reduction of metal nano-particle was introduced to reduce Fe3O4 onto the graphene surface. By using Scanning Electron Microscope, Energy Dispersive Spectrometer, X-ray Diffractometer and also doing BET analysis, resistivity test and TGA test, we obtained the optimal ratio for Graphene Oxide to FeCl2 is 1 g to 0.5 g.
The Fe3O4@Graphene powder at 0.1 wt%, 0.5 wt%, 1 wt%, 2 wt% and 3 wt% were added respectively to Nylon 6 through the in situ polymerization. The functional properties of these Nylon 6 composites were discussed by the results of FTIR, DSC, XRD, VSM, resistivity test and tensile test.
Due to the results we understand that Fe3O4@Graphene powder not only has great conductivity, but possesses electromagnetic effects. Adding the powder to Nylon 6 could enhance its electromagnetic property. Adding 0.1 wt% Fe3O4@Graphene powder, it could strengthen the mechanical property of Nylon 6. Furthermore, while the adding amount was 3 wt%, it could reduce the resistivity by 2 levels, but VSM showed that the composites presented obvious electromagnetic property.
