摘要
Nylon 1212/organic montmorillonite(OMMT)nanocomposites were prepared using the melt compounding method.The morphology and dynamical mechanical properties of the nanocomposites were investigated using transmission electron microscope(TEM)and dynamic mechanical analysis(DMA).The storage modulus of nylon 1212/OMMT nanocomposites was increased with increasing OMMT.The flame retardant properties were characterized by cone calorimetry,scanning electron microscope(SEM)and X-ray photoelectron spectroscopy(XPS).The flame retardant properties were characterized using cone calorimetry,whereby nylon 1212/OMMT nanocomposites were improved compared with pure nylon 1212 because of the carbonaceous-silicate granular materials which were formed during combustion,thus proposing the flame retardant mechanism.
