چکیده
|
Graphene naonosheets were prepared via one-pot hydrothermal process in a teflon-lined autoclave. moreover,the mechanical and thermal degradation behaviors of the phenol formaldehyde/carbon nanotubes and phenol formaldehyde/graphene naonosheets composites were discussed. experimental results showed that the graphene naonosheets possessed better performances than that of carbon nanotubes. when the filler loading was 0.6wt%,tensile strength,young's modulus,compressive strength and modulus of the as-prepared composites reached their maximum values,which were increased by 77.0,141.3,109.1 and 114.8% for graphene naonosheets and 54.7,85.9,61.7 and 45.2% for carbon nanotubes than those of pure sample,respectively. in addition,both of these two carbon materials could increase the thermo-stability of the matrix. when their usage amount was 0.6wt%,the thermal degradation temperature (at 10% weight loss) was increased to 255.6°c for phenol formaldehyde/graphene naonosheets composites and 253.5°c for phenol formaldehyde/carbon nanotubes composites from 233.6°c for pure sample.
