摘要：

Graphene (Gr)/poly(vinylidenefluoride-co-trifluoroethylene) (P(VDF-TrFE)) composite films were annealed by the photothermal effect that produced between near-infrared laser and graphene. Raman spectra, X-ray Diffraction (XRD), Fourier-Transformed Infrared Spectroscopy (FTIR), Differential scanning calorimetry (DSC) are used to characterize the crystalline state of Gr/P(VDF-TrFE) films. Further, piezoelectric coefficient d33 were to test polarization performance. Finally, the Bovine serum albumin (BSA) adsorption shows that annealing and polarization of Gr/P(VDF-TrFE) films are important for protein adsorption.
