“…Pure polymers are easy to process into mechanically robust components but generally suffer from low dielectric constant [3,4]. On the other hand, typical high-dielectric constant materials, such as ferroelectric ceramics, are brittle and require high-temperature processing [5] which are often not compatible with current circuit integration technologies.…”

Nano crystalline powders of Barium Sodium Niobate (BNN) with the composition Ba3–2x Na4+x R Nb10 O30 with (R stands for rare earth = 0, x = 0) have been prepared by conventional ceramic technique. Barium Sodium Niobate can form a wide range of solid solutions, incorporating rare earth and alkali, alkaline earth elements with different compositions. The powder belonged to tungsten bronze type structure with tetragonal symmetry and lattice constants a = b = 1.2421 nm and c = 0.3903 nm. XRD (X-ray Diffraction) SEM (Scanning Electron Microscope) and AFM (Atomic Force Microscope) studies revealed that the particle size is in the nanometer range. Composites are prepared by mixing powders of BNN with polystyrene at different volume fractions of the BNN. Melt mixing technique is carried out in a Brabender Plasticoder at a rotor speed of 60 rpm (rotations per minute) for composite preparation. Mechanical properties such as stress-strain behavior, Young’s modulus, tensile strength, strain at break etc. are evaluated. Addition of filler enhances the mechanical properties of the polymer such as Young’s modulus and tensile strength. The composites showed the trend of perfect adhesion between the filler and the polymer. The filler particles are distributed relatively uniform fashion in all composites and the particles are almost spherical in shape with irregular boundaries. To explore more carefully the degree of interfacial adhesion between the two phases, the results are analyzed by using models featuring adhesion parameter. The experimental results are compared with theoretical predictions

“…Piezoelectric polymers such as poly-vinylidene fluoride (PVDF) and its copolymers possessed low mechanical quality factor (Q m ) and acoustic impedance, but their piezoelectric strain constants (d 33 ) were much lower than those of piezoelectric ceramics [1,2]. Recently, various 0-3, 1-3, 2-2 composites of piezoelectric ceramics and polymers which combine the superior properties of both and offer many advantages over the constituent materials have been fabricated [3][4][5]. Among those, 0-3 connectivity was considered to be comparatively easy to be mass produced.…”

0-3 type composites based on pre-poled Pb(In 1/ 2 Nb 1/2 )O 3 -Pb(Mg 1/3 Nb 2/3 )O 3 -PbTiO 3 (PIN-PMN-PT) ceramic and poly-vinylidene fluoride (PVDF) have been fabricated. The dielectric and piezoelectric properties of the 0-3 composites were studied as a function of ceramic volume fraction. The results showed that the dielectric constant e r and piezoelectric strain constant d 33 were enhanced with an increase of ceramic volume fraction. The composites possessed lower acoustic impedance and better flexibility comparing to the PIN-PMN-PT ceramic with the same composition, but their acoustic impedance Z and elastic stiffness coefficient C 33 presented an abnormal decrease trend when a high volume fraction of ceramic ([80 %) was loaded in the composites. Since the Curie temperature of the PIN-PMN-PT ceramic reinforcement phase was much higher than the melting point of PVDF, pre-poled ceramic phase could keep its polarization during the subsequent complex processing. By comparing the dielectric and piezoelectric properties of composites using pre-poled ceramic with those using virgin one, it was found that pre-polarization of the PIN-PMN-PT reinforcement phase could improve the performance of these 0-3 type ceramic/polymer composites.

“…By changing the proportion of the constituents, their property can be varied according to the applications. Pure polymers are mechanically strong components but generally suffer from low dielectric constant [1,2]. Whereas, typical high dielectric constant materials such as ferroelectric ceramics are brittle and requires a high-temperature processing [3].…”

A metal-ferroelectric-insulator-semiconductor (MFIS) structure has been made using poly(vinylidene difluoride-trifluoroethylene)/barium titanate [P(VDF-TrFE)/ BaTiO 3 ] nanocomposite as ferroelectric layer, on silicon/ silicon dioxide (Si/SiO 2 ) substrate. Different concentrations of BaTiO 3 were added to P(VDF-TrFE) polymer using bath sonication method, and the films were prepared using spin coating method. The structure was annealed to 120°C for 2 h and then the top aluminium electrode was deposited by thermal evaporation method. Capacitancevoltage shows an increase in accumulation capacitance as the BaTiO 3 nanoparticle concentrations increases. Dielectric constant was estimated from the capacitance voltage (C-V) characteristics and found to be changing as the concentration of BaTiO 3 is varied. Polarization-electric field analyses show hysteresis behaviour of the nanocomposite. A comparison of MFIS and metal-ferroelectricsemiconductor structures was done with varying ferroelectric film thicknesses. All these results suggest that this polymer nanocomposite can be a promising material which can be used in non-volatile memory devices.
