AB  - Due to the excellent mechanical, thermal and electrical properties, 
      graphene/polymer composite is expected to have a variety of applications in 
      analytical chemistry. In this study, a new poly(ethylene glycol 
      dimethacrylate)/graphene composite was prepared by in situ polymerization. The 
      new composite was used for the first time as the extraction coating of stir rod 
      sorptive extraction for the preconcentration of polycyclic aromatic hydrocarbons 
      (PAHs) from water samples. Because of the high specific surface area and pi-pi 
      electrostatic stacking properties of graphene, the graphene-polymer composite 
      showed higher extraction efficiencies towards most target PAHs from water samples 
      than the neat polymer. Under the optimal conditions, a method for the 
      determination of PAHs in water samples was proposed based on the combination of 
      stir rod sorptive extraction (SRSE) and gas chromatography-mass spectrometry 
      (GC-MS). The limit of detection (LODs) of the developed method for 16 PAHs ranged 
      from 0.005 to 0.429 ng mL-1, depending on the compound. Good reproducibility of 
      method was obtained as intra- and inter-day precisions, the relative standard 
      deviations (RSDs) were less than 12.5% and 12.6%, respectively.
