Fabrication and characterization of metal-core carbon-shell nanoparticles filling an aeronautical composite matrix

摘要: Abstract Metal nanoparticles (NPs) were prepared from acrylamide complex of iron and nickel nitrates by controlled thermolysis at constant temperature in a self-generated atmosphere used to fabricate epoxy resin nanocomposites. X-ray diffraction performed on the revealed metal core/polymeric shell structure for thermolysed higher as also confirmed cross analysis thermo-gravimetrical vibrating magnetometer data. Optical microscopy was investigate achieved dispersion within uncured transmission electronic analyse morphology average dimensions nanoparticles. Thermal stability manufactured nanocomposites studied thermo-gravimetric inert oxidative conditions, reporting that negligible variations are induced presence nanofillers. A complete thermo-mechanical fracture characterization carried out assess effect final nanocomposite system. slight increase modulus is recorded room whereas significant variation temperature. The induces global energy associated different failure mechanisms. Magnetic data indicate particles based display room-temperature ferromagnetic behaviour with saturation magnetization coercivity depending diameter core.
