One‐step synthesis of graphene nanoplatelets/SiO 2 hybrid materials with excellent toughening performance
Source abstract
Abstract
Graphene nanoplatelets (GNPs)/SiO 2 hybrid materials had been prepared successfully via chemical grafting in one step. Herein, SiO 2 particles and GNPs were connected by poly acryloyl chloride (PACl). The results from Fourier transform infrared spectroscopy showed that functionalized GNPs and SiO 2 particles had been successfully bridged with chemical bonds like OCO and SiOC. And the nanostructure of hybrid materials was characterized by scanning electron microscopy and transmission electron microscopy. All the images indicated that SiO 2 particles were grafted on the surface of GNPs successfully. Moreover, the result of Raman spectroscopy showed that carbon atoms of GNPs became much more disorder, due to destroying the carbon domains during the process of chemical drafting. Meaningfully, the results from tensile tests indicated that Graphene/SiO 2 hybrid materials had better toughening effect on epoxy composites than graphene oxide and SiO 2 particles. POLYM.
