Inorganic nanotubes reinforced polyvinylidene fluoride composites as low-cost electromagnetic interference shielding materials
Novel polymer nanocomposites comprising of MnO2 nanotubes (MNTs), functionalized multiwalled carbon nanotubes (f-MWCNTs), and polyvinylidene fluoride (PVDF) were synthesized. Homogeneous distribution of f-MWCNTs and MNTs in PVDF matrix were confirmed by field emission scanning electron microscopy. Electrical conductivity measurements were performed on these polymer composites using four probe t...
متن کاملElectromagnetic interference (EMI) shielding of single-walled carbon nanotube epoxy composites.
Single-walled carbon nanotube (SWNT)-polymer composites have been fabricated to evaluate the electromagnetic interference (EMI) shielding effectiveness (SE) of SWNTs. Our results indicate that SWNTs can be used as effective lightweight EMI shielding materials. Composites with greater than 20 dB shielding efficiency were obtained easily. EMI SE was tested in the frequency range of 10 MHz to 1.5 ...
متن کاملTitle : PMMA / carbon nanotube nanocomposites foams for EMI shielding application
With the rapid development of gigahertz electronic systems, electromagnetic pollution has become a serious problem, which justifies a very active quest for effective electromagnetic interferences (EMI) shielding materials. Polymers filled with carbon fillers have been widely investigated for EMI shielding purposes because of unique combination of electrical conductivity and polymer flexibility....
متن کاملThermal Stability and Magnetic Properties of Polyvinylidene Fluoride/Magnetite Nanocomposites
This work describes the thermal stability and magnetic properties of polyvinylidene fluoride (PVDF)/magnetite nanocomposites fabricated using the solution mixing technique. The image of transmission electron microscopy for PVDF/magnetite nanocomposites reveals that the 13 nm magnetite nanoparticles are well distributed in PVDF matrix. The electroactive β-phase and piezoelectric responses of PVD...
متن کاملThe influence of single-walled carbon nanotube structure on the electromagnetic interference shielding efficiency of its epoxy composites
Three types of single-walled carbon nanotube (SWCNT) homogeneous epoxy composites with different SWCNT loadings (0.01–15%) have been evaluated for electromagnetic interference (EMI) shielding effectiveness (SE) in the X-band range (8.2–12.4 GHz). The effect of the SWCNT structure including both the SWCNT aspect ratio and wall integrity, on the EMI SE have been studied and are found to correlate...
