Enhanced thermal and mechanical properties in functionalized graphene nanosheets/epoxy composites by simple sol-gel method |
| 초록 |
Functionalized graphene(FG)/epoxy composites were prepared using the epoxy resin diglycidyl ether of bisphenol A. Graphene oxide (GO) and Al(OH)3-coated graphene (Al-GO) fillers were fabricated using the Hummers method and a simple sol-gel method, with aluminum isopropoxide. The FGs were characterized by XPS, FE-SEM and TEM. These analyses confirmed that the Al(OH)3 layer could have a homogeneous distribution onto GO sheets. The storage modulus and tan δ graphs illustrate the enhancement achieved by increasing the filler function. The thermal conductivities of the composites with graphene-based fillers were enhanced by the addition of fillers. In particular, the thermal conductivity of GO/epoxy composite containing 3 wt% was approximately 2 times higher than that of pure epoxy resin. The electrical conductivity of Al-GO embedded composites degenerated compared to GO composites. |
