Poly(methyl acrylate) (PMA)–tetrapropylammonium iodide (TPAI) and poly(vinyl acetate) (PVAc)–TPAI solid polymer electrolytes were prepared by solution casting method. DSC, FTIR, and conductivity results are reported. TPAI interacts with PMA and PVAc to form PMA–TPAI and PVAc–TPAI complexes. Formation of PMA–TPAI and PVAc–TPAI complexes are supported by the DSC and FTIR studies. Linear relationship...
Innovative advance dielectric materials were utilized to fabricate novel thin film capacitor device. This includes ceramic and polymeric material combination which is considered to enhance the dielectric polarization. The dielectric film presented in the study focused on PbTiO3/PVDF-TrFE which was prepared through layer-by-layer spin coating deposition method. The PVDF-TrFE coating was aimed to encapsulate...
Hybrid composited material like polymer-ceramic will improve the reliability factor of the device. Yet, the motivation still goes on to produce high performance device. In this study, the impedance analysis on bilayer films lead titanate and poly(vinyledenefluoride-trifluoroethylene) yield to the semicircle cole-cole plot with added slanted spike results. This presents the double layer capacitance...
Metal–insulator–metal (MIM) capacitors based on lead titanate (PbTiO3) nanofilms were prepared using a novel method involving modified spin coating onto the bare electrodes of a coated glass. Different solutions were prepared by adding different concentrations of lead acetate (PbAc) powder to improve the electrical properties of the PbTiO3 films. The nanofilms were characterized in terms of their...
Magnesium oxide and bilayer ZnO/MgO dielectrics film were successfully deposited using spin coating technique. The effect of MgO layer thickness towards prepared dielectric films behaviour was determined by controlling the deposition time. The comparison of the MgO and ZnO/MgO dielectrics film properties shows that the bilayer ZnO/MgO with 238nm MgO layer thickness shows better dielectrics properties...
This study investigates the effect of varying loading percentage of MgO on the dielectric constant of Poly (vinylideneflouride)/Magnesium Oxide (PVDF/MgO) nanocomposite thin films. PVDF/MgO nanocomposite spin coated thin films were successfully fabricated and characterized. PVDF and nanocomposites solutions with loading percentage of MgO at 3, 5, 7, 9, and 11% were spin coated on Al-glass substrates...
The morphology of PVDF-TrFE (70/30) thin film at various annealing temperature were investigated using non-contact mode Atomic Force Microscopy (AFM). Differential Scanning Calorimetry (DSC) technique was used to obtain TC, Tm, and TCrys of PVDF-TrFE. The prepared spin coated PVDF-TrFE (70/30) thin films were annealed at TC (113°C), Tm (154°C), TCrys (135°C) and Tc at cooling (55°C) in accordance...
