This book was released on 2013 with total page 60 pages. Available in PDF, EPUB and Kindle. Book excerpt: Polymer nanocomposites were prepared via room temperature mixing of polydimethylsiloxane (PDMS) and polyurethane (PU) elastomers as base matrices and titania nanoparticles (both normal and heat treated) as filler material. In case of polyurethane-titania nanocomposites two different mixing methods were used whereas polydimethylsiloxane-titania nanocomposites were prepared using two different types of titania particles, namely normal and heat treated ones. Different characterization techniques like fourier transform infrared (FTIR) spectroscopy, X-ray diffraction (XRD), thermogravimetric analysis (TGA), dynamic light scattering (DLS), high resolution transmission electron microscopy (HRTEM), field emission scanning electron microscopy (FESEM), and scanning probe microscopy (SPM) were used for these composites. The composition dependent electrical resistivity and dielectric properties of these composites were also measured. The effect of pressure on both DC resistivity and dielectric constant was studied for the PU-TiO2 nanocomposites and found that both resistivity and dielectric constant changes with applied pressure which is again composition dependent.

This book was released on 2022-09-23 with total page 255 pages. Available in PDF, EPUB and Kindle. Book excerpt: This monograph provides researchers, engineers, postgraduates and lecturers working in the field of ferroelectric or piezoelectric and related materials with features of the structure-property relationships in modern piezo-active composites. These are piezoelectric composites which are active dielectric materials, which can be poled ferroelectric ceramics or domain-engineered single crystals poled along specific crystallographic directions. Current knowledge of the effective physical properties of these materials is lacking especially due to gaps of information in physical, chemical, microgeometric and technological factors. For composite and transducer design purposes, the expected properties of these piezo-active materials have been theorized through models by the authors and proven in experiments. Various well-known journals have published this research, among many others: Smart Materials and Structures; Journal of Physics D: Applied Physics; IEEE Transactions on Ultrasonics, Ferroelectrics, and Frequency Control; Acta Materialia.The book summarises and generalises a series of authors' works on the problem of the effective properties and related parameters of modern two- and three-component piezo-active composites wherein the microgeometric factor plays the dominating role. Specific examples of the performance of composites based on domain-engineered single crystals are also discussed. New trends are described in the research of modern piezo-active composites with the aim of filling the gaps in piezoelectric materials science. The primary goal of the book is to show advantages of different methods being applied to manufacture and study the functional composites that are suitable for piezoelectric energy harvesting, hydroacoustic, sensor, actuator, and other transducer applications.

Download or read book Ferroelectric Piezoelectric and Dielectric Properties of Novel Polymer Nanocomposites written by Maheswar Panda and published by . This book was released on 2018 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: In this chapter, the Ferroelectric, Piezoelectric and Dielectric behavior of novel polymer/ceramic nano-composite (PCC) based on ferroelectric polymer [polyvinyledene fluoride (PVDF)] & nano Barium Titanate (n-BaTiO3) with different volume fractions of n-BaTiO3 (fBaTiO3), prepared through the novel cold pressing method has been discussed. The ferroelectric parameters of PCC are attributed to spherulites of PVDF, the increase of n-BaTiO3 and the ordered homogenous structure due to the novel cold pressing. The clustering of ceramic fillers is responsible for randomization of the structures of these composite ferroelectrics for some samples, leading to decrease of electrical polarisations. The piezoelectricity and piezoelectric coefficients of these composites ferroelectrics, increases with increase of ceramic filer content and remains constant beyond a certain ratio. However, the dielectric properties increase linearly as a function of ceramic content due to increase of interfaces/interfacial polarisations. The enhancement of effective dielectric constant (...õeff) is attributed to the large interfacial polarization arising due to the charge storage at the spherulites of PVDF and at the polymer/filler interfaces of PCC and have been explained on the basis of sum effect with the help of the standard models. The achieved lower loss tangent (Tan Œ¥) for the PCC as compared to the polymer/metal composites (PMC) is attributed to the highly insulating nature of PVDF & semiconducting n-BaTiO3. The thermal stability of the composites is also maintained due to the higher melting temperature (170¬∞C) of PVDF. The cold pressed PCC based on PVDF are going to act as better polymer ferroelectric/dielectrics for memory and electrical energy storage applications.
