Correlations between fatigue and variations in material constants of PLZT ceramics
Adrijan Levstik, Vid Bobnar, Zdravko Kutnjak, Marija Kosec
Izvirni znanstveni članek
Oznake: PLZT;fatigue;piezoelectric resonance;electromechanical properties;
Correlations between fatigue and material constants of bulk 8/65/35 PLZT ceramics were investigated by a simultaneous measurement of faatigue and piezoelectric resonance as a function of switching cycles. It was found that as remanent polarization, also the real and imaginary paarats of the complex ...

Origin of enhanced dielectric tunability in antiferroelectric ceramic systems
Vida Jurečič, Tadej Rojac, Vid Bobnar, Nikola Novak
Izvirni znanstveni članek
Oznake: dielectric tunability;materials;
Antiferroelectric ceramics are considered as highly promising materials for the development of novel DC-link, snubber, and filter capacitors used in high-power and high-speed electronics for electromotive and renewable energy applications, medical equipment, and weapons platforms. In particular, the ...

Percolative dielectric behavior of titanium carbide MXene/cellulose nanofibrils composite films
Vida Jurečič, Subramanian Lakshmanan, Nikola Novak, Vanja Kokol, Vid Bobnar
Izvirni znanstveni članek
Oznake: percolation theory;
Cellulose-based nanomaterials are fascinating renewable biosystems, yet low thermal conductivity and dielectric permittivity often limit their potential applications in flexible electronics. We report dielectric properties of composite films prepared by vacuum filtration or solvent casting method fr ...

Izvirni znanstveni članek
Oznake: polimerna mešanica;mehanske lastnosti;kristalizacija;polymer blend;mechanical properties;crystallization;
In this research, the influences of the addition of PVP to PVDF-HFP polymers and the preparation of thin films using a solvent casting method were studied. The PVDF-HFP and polymer blend PVDF-HFP/PVP thin films with a nanostructured surface were investigated using scanning electron microscopy, diffe ...
