- Abstract
Carbon nano tube (CNT) is a promising reinforcing material in epoxy resin, because of its unique mechanical properties. CNTs aggregate easily due to their nano-properties, so it is important to disperse CNTs in epoxy resin uniformly when producing CNTs reinforced epoxy resin composite. Twin rotor mixer was used to disperse different amount of CNTs in epoxy resin with various parameters of revolutions per minute (rpm), duration and mixing temperature. Transmission electron microscope (TEM) was used to observe the dispersion results. It indicated that higher rpm and longer duration resulted in better dispersion, while the mixing temperature effected a little. Mixing 0.5 wt.% CNTs in AG80 epoxy resin at 600 rpm and lasting for 20 min resulted in the best dispersion. Furthermore,to improve the dispersibility of CNTs in acetone or epoxy resin, various surfactants were added. The result indicated that BYK-9077 modified CNTs dispersed best in both acetone or epoxy resin.
