Abstract

The effects of an ε,-Caprolactam (CL) modified nanosilica (MNS) component on thermal properties, morphology and rheological behavior of PA6/SiO2 nanocomposites were Investigated. Star-shaped PA6/SiO2 nanocomposites were synthesized through a Two-step In situ anionic rIng-openIng polymerization (AROP) of CL monomer by hexamethylene diisocyanate (HDI) lInkIng the nanoparticles and CL In a reactive melt blendIng. The star-shaped structure was observed by field emission scannIng electron microscope (FESEM) and elemental mappIng. Moreover, the study on chemical structure of the samples was carried out by Fourier transform Infrared (FTIR), energy-dispersive X-ray spectroscopy (EDX) and carbon nuclear magnetic resonance (13C NMR) spectroscopy. IncorporatIng MNS Increased γ,-crystal and arm numbers of the star-shaped structure. Thermal degradation Increased In the star-shaped samples due to the effects of MNS and molecular weight (MW). However IncreasIng the number of arms was effective In IncreasIng the temperature of degradation. In addition, the crossover of storage modulus (Gʹ, ) and loss modulus (Gʺ, ) shifted to higher frequencies In the low-and lower frequencies In the Inherit;color:#ff0078">Multi-arms star-shaped samples.
