Improving piezoelectric properties of PVDF polymer with use of Graphene Oxide Nano sheets

Poly Vinylidene Fluoride (PVDF) polymer beside of its fantastic thermal, chemical and physical properties have some polymeric phases include; α, β, γ and etc. because the β-phase produce the electric dipole moment, this phase known as the piezoelectric phase. GO Nano sheets when blending with PVDF polymer (PGO) can enhance the β-phase and improve PVDF piezoelectric properties. The PVDF and PGO samples are prepared by thermal induce phase separation (TIPS), RAMAN spectra indicate homogeneous dispersion of GO sheets in PVDF matrix. XRD and FTIR spectra confirm the improve the β-phase in PGO composite sample.
