One kind of nanocomposite consisting of graphene and polypyrrole was synthesized via a facile and mild way with the assistant of microwave irradiation. The synthesis route was embedding the polypyrrole into the graphene flakes to form a 3D structure, to achieve larger active surface and higher electro-catalysis property. Structures and components of the composite were measured by X-ray diffraction, field emission scanning electron microscopy, and Fourier transform infrared spectroscopy. A stronger electrochemical response of electrode with modified resultant was observed in the electrochemical test. Dopamine sensor based on the composite showed a sensitivity of 363 μA mM−1 cm−2, a linear range of 1 × 10−4 M to 1 × 10−3 M, and a detection limit of 2.3 × 10−6 M (S/N = 3). © 2017 Wiley Periodicals, Inc.
