      and Reduced Graphene Oxide.

AB  - This study was dedicated to the investigation of poly(vinylidene fluoride) (PVDF) 
      micropillar arrays obtained by soft lithography followed by phase inversion at a 
      low temperature. Reduced graphene oxide (rGO) was incorporated into the PVDF as a 
      nucleating filler. The piezoelectric properties of the PVDF-rGO composite 
      micropillars were explored via piezo-response force microscopy (PFM). Fourier 
      transform infrared spectroscopy (FTIR) and X-ray diffraction (XRD) showed that alpha, 
      beta, and gamma phases co-existed in all studied samples, with a predominance of the gamma 
      phase. The piezoresponse force microscopy (PFM) data provided the local 
      piezoelectric response of the PVDF micropillars, which exhibited a 
      temperature-induced downward dipole orientation in the pristine PVDF 
      micropillars. The addition of rGO into the PVDF matrix resulted in a change in 
      the preferred polarization direction, and the piezo-response phase angle changed 
      from -120 degrees  to 20 degrees -40 degrees . The pristine PVDF and PVDF loaded with 0.1 wt % of rGO 
      after low-temperature quenching were found to possess a piezoelectric response of 
      86 and 87 pm/V respectively, which are significantly higher than the |d(33)(eff)| 
      in the case of imprinted PVDF 64 pm/V. Thus, the addition of rGO significantly 
      affected the domain orientation (polarization) while quenching increased the 
      piezoelectric response.
