The study of mechanical and electrical properties of vitrimer filled with Mulltiwalled carbon nanotubes |
| 초록 |
The epoxy/ multi-walled carbon nanotubes (MWCNTs) composites was fabricated using fatty acid for flexiblility of epoxy composites. vitrimer has recycling and flexibility property because fatty acid linker typically possesses longer backbone chain, and hence has more freedom of motion at given temperature. The curing behavior and glass transition temperature (Tg) of vitrimer were analyzed using Differential Scanning Calorimeter (DSC) and Dynamic mechanical analysis (DMA). For high electrical conductivity of composites, MWCNT was used as a conductive filler and confirmed that percolation threshold by Dielectric Analysis (DEA). The high aspect ratio (L/D) of MWCNT shows the low percolation threshold due to formation of conducting path. The mechanical properties of vitrimer filled MWCNT was measured by Universal Testing Mechine (UTM). The tensile strength and adhension propertises were increased due to improvement of Van der waals interation in matrix |
