Inkjet printing has been wide-spread recognized as a drop-on-demand printing technologies capable of depositing quantities of material accurately. With this technique, automatic processing and electroactive polymeric components design seems practical. However the physico-chemical properties of printed electroactive polymer highly depend upon the solution comprising because the defined post-printing area must undergo both volatilization and crystallization process. In current studies two solvent with quite different volatility, methyl ethyl ketone (MEK, b.p. 79.64°C ) and triethyl phosphate (TEP, b.p. 215°C) for inkjet printing ink solvent for solubilizing poly(vinylidene-fluoride trifluoroethylene chlorotrifluoroethylene)[P(VDF-TrFE-CTFE)] relaxor ferroelectric powders were compared by analyzing resultant polymers. Pristine polymers of both solvents were prepared by depositing solution on PET substrate and annealed at given temperature. Curie and melting regimes were firstly monitored by differential scanning calorimetry and TEP polymers showed higher crystallinity over MEK counterparts but decreasing Curie enthalpy and transition points. Effects of solvent parameters on molecular dynamics were investigated by broadband dielectric spectroscopy, showing that TEP polymer exhibited the slowing down of segmental dynamics with increased Vogel temperature in amorphous and higher curie transition activation energy in crystal phase. Additional, due to presence of large Maxwell–Wagner–Sillars polarization, enhanced dielectric permittivity was observed at low frequency for TEP polymer. Influences on electrostrictive behavior were finalized and verified by unimorph bending mode. TEP polymer behaved larger tip displacement but equivalent free mechanical energy density (Y*S31^2/2) was obtained due mostly to its relatively low transverse stain (S31) and high Young’s modulus (Y). Such results intended to give contribution to the behaviors of drop-on-demand inkjet printing films.
