A thin film of pyroelectric composite with 0–3 connectivity was fabricated from zinc oxide (ZnO) nanopowder and polyvinylidene fluoride (PVDF) different volume fraction 0–0.25 wt%. The dielectric properties the samples were investigated. It found that presence a small amount ZnO nanoparticles (0.25 wt%) has significantly increased coefficient PVDF by 25%. Furthermore, nanocomposite films required lower poling field to form polar-δ phase compared pure films. Analysis complex permittivity in...
ZnO nanoparticles (ZnO-NPs) were synthesized by a new, simple sol-gel method in gelatin media (particle size of ≈ 30 to 60 nm). Polyurethane/ZnO nanocomposites thin films (PU/ZnO-NPs) prepared mixing the ZnO-NPs into PU prepolymer. The structurally characterized using Fourier transmission infrared (FTIR) spectroscopy. interaction between and matrix is studied analyzing differences C=O region N-H FTIR spectra. morphology PU/ZnO assessed electron micrograph, TEM, field emission scanning...
A hybrid piezo/triboelectric nanogenerator (H/P-TENG) is designed for mechanical energy harvesting using polymer ceramic composite films; polydimethylsiloxane/Ba(Zr 0.2 Ti 0.8 )O 3 –0.5(Ba 0.7 Ca 0.3 )TiO (PDMS/BZT–BCT) and polyvinyl alcohol (PVA).

An enhanced contact electrification process in P-TENGs caused by piezoelectric polarization.
The effects of solvents and temperature on the crystal formation were investigated for vinylidene fluoride/trifluoroethylene copolymer P(VDF-TrFE). Highly crystalline P(VDF-TrFE) thin films fabricated by spin-casting using various polar such as diethyl carbonate (DEC), methyl ethyl ketone (MEK), N,N-dimethylformamide (DMF) dimethyl sulfoxide (DMSO). Ferroelectric polarisation reversal was evidenced a displacement (D)-electric field (E) hysteresis loop measurement supported presence...
Abstract Three different polyester polyols, with various oleic acid content, were used in the preparation of polyurethane (PUR) coatings. The polyols designated as Alk28, Alk40, and Alk65, which 28, 40, 65 represent percentage polyol formulations. These reacted aromatic diisocyanate [toluene (TDI)] to form PUR value, hydroxyl molecular weight, viscosity have been determined. reaction between TDI was studied by Fourier Transform Infrared spectroscopy X‐ray diffraction (XRD). effects varying...
Glycolipid, found commonly in membranes, is also a liquid crystal material which can self-assemble without the presence of solvent. Here, dielectric and conductivity properties three synthetic glycolipid thin films different thermotropic phases were investigated over frequency temperature range (10(-2)-10(6) Hz) (303-463 K), respectively. The observed relaxation processes distinguish between (smectic A, columnar/hexagonal, bicontinuous cubic Q) molecular structures. Large responses columnar...
