Graphene is used in many polymer composites due to its excellent electrical, mechanical and barrier properties. The graphene oxide has various oxygen-containing groups such as epoxide, hydroxyl and carboxyl groups. Additives are used for various polymers to improve the physical properties of polymer, to improve the processability and the product quality, and to reduce the manufacturing cost. The acrylic oligomers of molecular weight 3000 - 4000 were prepared by controlling the reaction conditions without using the chain transfer agent in order to apply as additives. Oligomer, which was synthesized using both N-vinylpyrrolidone and butyl acrylate, was used to modified the graphene oxide surface. The acrylic oligomer modified graphene oxide played the important role of additive to improve the electrical properties of polymer composites. |
