“…16a presents the X-ray pattern of the film. It is clear from the patterns that most intense reflection occurs at 2h-30.98 o , which is very close to the value mentioned in the literature (Daben 1990) for PVDF-PZT nanocomposite. The intensity of (110) reflection increases as the PZT concentration increases from 10 to 50 wt%.…”

“…Nanocomposites also possess structural and electrical properties that can be tailored by controlling its composition to make them suitable for transducer applications. Piezoelectric PMNC consists of piezoelectric nanofillers like PZT, zinc oxide (ZnO) embedded in a polymer matrix (Daben 1990;Jain et al 2014;van den Ende et al 2007;Meyers et al 2013). These nanofillers impart piezoelectricity simultaneously retaining the properties of the polymer.…”

This paper reviews the potential of polymer and ceramic matrix composites for aerospace/space vehicle applications. Special, unique and multifunctional properties arising due to the dispersion of nanoparticles in ceramic and metal matrix are briefly discussed followed by a classification of resulting aerospace applications. The paper presents polymer matrix composites comprising majority of aerospace applications in structures, coating, tribology, structural health monitoring, electromagnetic shielding and shape memory applications. The capabilities of the ceramic matrix nanocomposites to providing the electromagnetic shielding for aircrafts and better tribological properties to suit space environments are discussed. Structural health monitoring capability of ceramic matrix nanocomposite is also discussed. The properties of resulting nanocomposite material with its disadvantages like cost and processing difficulties are discussed. The paper concludes after the discussion of the possible future perspectives and challenges in implementation and further development of polymer and ceramic nanocomposite materials.

“…The dielectric permittivity of the PVDF + 0.4KTNO composite at 1 kHz is as high as 400. Such a high-of the composite could be explained using the said percolation theory [23][24][25][26]28,29 because of semiconducting 11 behavior of KTNO.…”

“…At this stage, the conduction behavior of the composites is controlled by the concentration of KTNO phase. The electrical property of the composites with composition near the percolation threshold follows a scaling law [23][24][25] ͓see Eqs. ͑4͒ and ͑5͔͒.…”

Homogeneous thick film (∼0.10 mm) of high dielectric K0.05Ti0.02Ni0.93O; abbreviated as KTNO/polyvinylidene fluoride (PVDF) composite has been prepared by hot-molding technique. The frequency and temperature dependent dielectric behavior of this composite has been studied by varying the KTNO volume fraction (fKTNO). Near the percolation threshold (fKTNO=0.40), a large enhancement of effective dielectric permittivity (εeff∼400 which is 40 times higher than that of pure PVDF) with low loss (∼0.20 at 1 kHz) is observed. The experimental εeff data have been fitted with different theoretical models and found to follow percolation theory successfully. Such a high εeff and low loss flexible dielectric material appears to be suitable for technological applications.

“…The requirement can be optimized by combining the most useful properties of the two phases which do not ordinarily appear together. The main advantage of composites made of electroactive ceramics and a ferroelectric polymer rest with their high electrostrictive, piezoelectric, and pyroelectric properties, low acoustic impedance matching with water and human skin, and with the fact that their properties can be tailored to various requirements and they could be made practically in any shape or size [2,[9][10][11][12][13][14][15][16]. Properties of composites, i.e.…”
