摘要：
In this study, we report a simple and efficient method to prepare three-dimensional graphene oxide (3DGO) network by freeze drying and investigate the effect of 3DGO network on thermal properties of epoxy composites. It was found that the 3DGO network not only improved thermal conductivity, thermal stability, glass transition temperature and storage modulus of epoxy composites, but also reduced the thermal expansion properties of epoxy composites. For instance, the thermal conductivity value of epoxy composite with only 1.3 wt% 3DGO is 0.62 Wm(-1)K(-1), increased by 148 % in comparison with that of the neat epoxy (0.25 Wm(-1)K(-1)).
