Polyimide Nanocomposite Thin Films Containing Epoxy Functionalized Octavinylpentacyclo(Octasiloxane) with Low-Level Dielectric Constant for Electronic Devices

Poly (vinylideneflouride)/nanomagnesium oxide (PVDF/MgO) film with MgO loading percentage of 7% were annealed with various annealing temperatures ranging from 70°C to 170°C. The PVDF/MgO(7%) thin films were fabricated using spin coating technique with metal-insulator-metal (MIM) configuration and the dielectric constant of PVDF/MgO(7%) with respect to annealing temperatures was studied. The PVDF/MgO nanocomposite thin films annealed at temperature of 70°C (AN70) showed an improvement in the dielectric constant of 27 at 103 Hz compared to un-annealed sample (UN), which is 21 at the same frequency. As the annealing temperatures were increased from 90°C (AN90) to 150oC (AN150), the dielectric constant of PVDF/MgO(7%) were found to gradually decreased from 25 to 12 respectively, interestingly lower than the UN thin films. AN70 also produced low value of tangent loss (tan δ) at frequency of 103 Hz. The resistivity value of AN70 was also found to increase from 3.08×104Ω.cm (UN-PVDF) to 1.05×105Ω.cm. The increased in dielectric constant, with low tangent loss and high resistivity value suggests that 70°C was the favourable annealing temperature for PVDF/MgO(7%) for application in electronic devices such as low frequency capacitor.

Abstract—Poly (vinylideneflouride)/nano-magnesium oxide (PVDF/MgO) film with 7% MgO loading percentage was annealed at various annealing temperatures ranging from 70°C to 150°C. The PVDF/MgO thin film was fabricated using spin coating technique with a metal-insulator-metal (MIM) configuration. The dielectric and electric properties of PVDF/MgO with respect to annealing temperatures was studied. The PVDF/MgO nanocomposites thin films annealed at temperature of 70°C (AN70-PVDF/MgO) showed an improvement in the properties; dielectric constant value of 26 at 1 kHz frequency compared to un-annealed sample (UN-PVDF/MgO), which is 21 at the same frequency. As the annealing temperatures were increased from 90°C (AN90) to 150°C (AN150-PVDF/MgO), the dielectric constant values were found to gradually decreased from 25 to 12 respectively, which was lower than the UN-PVDF/MgO thin films. AN70-PVDF/MgO also produced relatively low tangent loss (tan δ). The resistivity value of AN70-PVDF/MgO was also found to increase from 3.08x104 Ω.cm (UN- PVDF/MgO) to 4.55x104 Ω.cm. The increased in the dielectric constant, with low tangent loss and high resistivity value suggests that 70°C was the favorable annealing temperature for PVDF/MgO film suitable for the application in electronic devices such as low frequency capacitor.

Surface Morphologies

The enhancement of ferroelectric and dielectric properties of PVDF-TrFE by incorporating various percentages of Magnesium Oxide (1 – 7%) for spin coated nanocomposite thin film was demonstrated. Observations showed uniform distribution and low agglomeration of MgO in the PVDF-TrFE nanocomposite thin film, especially for 3% MgO. Additionally, the 3% MgO incorporated into PVDF-TrFE had generated the highest Pr (88 mC/m2) and dielectric constant (13.6) in comparison other percentage compositions. However, the addition of more than 3% MgO filler loading caused a reduction in the ferroelectric and dielectric properties of the nanocomposite thin films.
