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. Various 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 2000 were prepared by controlling the reaction conditions without using the chain transfer agent in order to apply as additives. Oligomers from both N-vinylpyrrolidone and butyl acrylate were prepared on the graphene oxide surface during polymerization. As a result, the acrylic oligomer/graphene oxide composite played the role of additive to improve the electromagnetic interference shielding ability of polymer. |
