AB  - In order to further improve the performance of 0.94[(Bi0.5Na0.5)TiO3]-0.06BaTiO3/
polyvinylidene fluoride (NBT-BT/PVDF) flexible composite films prepared by the
hot-pressing method, the effect of surface modification of the NBT-BT particles on
the structure and properties of the films was investigated. Two coupling agents,
namely, (3-aminopropyl)triethoxysilane (APTES) and dodecyl triethoxysilane
(DDTES) were added to enhance dispersion and interfacial adhesion of the active
phase powder with the polymer matrix. The highest amount of the electroactive
PVDF β-phase was formed in APTES-modified samples while in DDTES samples
mainly γ-phase was formed as shown by Fourier-transform infrared spectroscopy
analysis. Differential scanning calorimetry measurements indicated that the addition
of filler particles reduced the total crystallinity degree of the PVDF. Dielectric
permittivity values as well as dielectric losses decreased for silanized samples due
to reduced tension at the interface between particles and polymer. Strong intermolecular
interaction between the PVDF chains and the APTES-modified particles
led to enhanced breakdown strength of these samples. The highest level of
agglomeration in the DDTES-modified samples induced the deterioration of ferroelectric
properties. The highest voltage output of  15 V and 225 μW of powerwas
obtained for the APTES-modified harvester, evidencing their potential for energy
harvesting applications.

AB  - U radu je predstavljen visokonaponski sistem za polarizaciju ultra
tankih filmova poliviniliden fluorida (PVDF) posredstvom visokonaponske korone.
PVDF je polimer sa jedinstvenim karakteristikama, kao što su piezoelektrične i
feroelektrične. Perspektiva primene ovih filmova je u sistemima za sakupljanje energije
iz mehaničkih vibracionih struktura koje generišu široki spektar učestanosti vibracija.
Veoma važan postupak koji obezbeđuje funkcionalnost proizvedenih PVDF tankih
filmova je visokonaponska polarizacija domena (tzv. polingovanje). Ovde su kvalitet i
preciznost visokog napona koji se generiše iz visokonaponskog energetskog pretvarača
veoma bitni sa aspekta kvaliteta polarizacije PVDF uzoraka. U radu je prikazan
konkretno realizovan visokonaponski energetski AC/DC pretvarač 230 V, 50Hz/0-5
kVdc, maksimalne izlazne snage 50 W, koji u potpunosti ispunjava tehničke zahteve
polarizacije PVDF uzoraka.
