Metals are often used as materials for electrical properties. However, these materials have disadvantages of heavy weight. Therefore, carbon materials such as carbon black, carbon fiber, and graphene are studied actively. The graphene oxide has various oxygen-containing groups such as epoxide, hydroxyl and carboxyl groups. The acrylic oligomers having molecular weight of 3000 - 4000 were prepared to be used as additives by varying the reaction conditions without using the chain transfer agent. Oligomer was synthesized with N-vinylpyrrolidone(NVP) and butyl acrylate as monomers with various NVP contents. When the content of NVP was above a certain level, the acrylic oligomer modified graphene oxide showed the noticeable improvement in the electrical properties of polymer composites. |
