Enhanced properties of phthalonitrile‐terminated polyarylene ether nitriles embedded with hybrid MWCNT–boehmite nanocomposites

摘要: The main motivation of the present work was to fabricate novel multifunctional polymer-based nanocomposites. nanocomposites embedded with multi-walled carbon nanotube-boehmite (MWCNT-boehmite) were prepared via hot pressure casting technique. MWCNT coated boehmite synthesized by hydrothermal synthesis. Subsequently, as-prepared MWCNT-boehmite added into phthalonitrile-terminated polyarylene ether nitriles (PEN-t-CN) matrix in order benefit from synergetic effect and boehmite. Scanning electron microscopy (SEM), transmission (TEM) X-ray diffraction (XRD), Fourier transform infrared (FTIR) employed confirm existence our article. Furthermore, structures, fracture morphologies, thermal, mechanical dielectric properties investigated, respectively. SEM images indicated that homogeneously dispersed polymer, which acted as an essential factor ensure good physical properties. TGA analysis showed incorporation enhanced thermal stability initial degradation temperature (Tid) increasing 458 492°C, while pure PEN-t-CN 439°C. testing proved significant enhancement has been achieved. tensile strength PEN-t-CN/MWCNT-boehmite composites 3 wt% reached maximum (78.33 MPa), a 41.7 % increase compared polymer. More importantly, unique systematically discussed results demonstrated exhibited little dependency on frequency. For hybrid filler, positive impact material resulted POLYM.
