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  - Energy  is  available  all  around  us  in  different  forms  and  shapes  such  as  from  sun,  wind,  waves,  vibrations  etc. The  enormous  amount  of  mechanical  energy  released  in  everyday  life  by  human  walking,  transportation   movement,   sound   waves   and   other,    represent   renewable   and   safe   energy   source.   Piezoelectric  generators  exhibit  a  great  potential  for  powering  up  low-power  portable  devices  and  self-powered  electronic  systems  by  extraction  of  mechanical  energy.  Employment  of  lead-free  piezoelectric  materials will  be  a  breakthrough  of  a  completely  new  type  of  safe  and  harmless  production  of  energy  for  daily life. Recent challenge in electronics is also utilization of flexible electronics with the ability to bend into diverse shapes which expands the applications of modern electronic devices in different areas.Polymer PVDF/piezoelectric ceramics,  flexible  composite  films  were  prepared  by  hot  pressing  method. The  influence  of  hot  pressing  method  on  the  formation  of  electroactive  PVDF  phases  in  the  polymer was proven by FTIR analysis.  DSC analysis have shown the change of PVDF crystallinity degree in  the  flexible  films  with  addition  of  ceramics  filler  particles.  The  dielectric  permittivity value  increased  with the addition of filler in the polymer matrix while the relaxation processes were governed mostly by the PVDF matrix. Polarization of flexible films enhanced the formation of PVDF electroactive β- phase in the samples. Energy  harvesting  potential  was  studied  by measuring  of voltage  output  under  the  impulse  hammer load.
