E-44 epoxy resin was used as matrix，and silicon nitride，boron nitride，alumina and silicon carbide were used as heat-conducting insulating fillers. By selecting the amounts and types of the insulting fillers, the heat conductive properties of E-44 could be adjusted. In addition, by choosing the curing agent and accelerator the viscosity of E-44 could also be readily controlled. The relation among the adhesive viscosity，heat conductive property and prescription was studied. When the amounts of silicon nitride, alumina and boron nitride were 25%, 25%, 10% (based on the mass of epoxy resin matrix), respectively, the thermal conductivity of this system was 2.66 W/mK.

π stacking and water-solubility of brilliant blue (BB) are expected to facilitate the hydrazine mediated reduction of graphene oxide (GO) in aqueous environment. Our newly-obtained BB-functionalized reduced graphene oxide (BB-rGO) exhibited excellent solubility and stability in water. The properties of BB-rGO were investigated. The results showed that the BB molecules stacked non-covalently onto the basal plane of rGO by strong π-π interactions while the sulfo groups of BB prevented the rGO from aggregation by electrostatic and steric repulsions, therefore leading to the solubility and stability of BB-rGO in aqueous dispersion.
