P(VDF-TrFE)/BaTiO3 nanocomposite Langmuir-Schaefer thin film for piezoelectric nanogenerator

Tuning the Electromechanical Response of P(VDF-TrFE)/ZnSnO3-Based Binary Piezoelectric Composites for Biomechanical Energy-Harvesting and Self-Powered Mechanosensing

“… − Although the host P­(VDF-TrFE) matrix and added ZnSnO 3 filler exhibit the negative and positive piezoelectric coefficients, respectively, this type of working mechanism helps in improving the overall energy-harvesting performances of the PENG devices up to a certain amount of filler loading, which might be attributed to better dipole alignment via interfacial interaction (Note S1). The improvement of piezoelectric energy-harvesting activity of unpoled P­(VDF-TrFE)-based PENG upon optimum loading of inorganic fillers having a positive piezoelectric coefficient is consistent with the previous literature. ,, …”

“…The 10PTR film exhibited the maximum value of | d 33 | of ∼37 pC/N. The improvement of the d 33 coefficient of P­(VDF-TrFE) for the optimum amount of inorganic piezoelectric filler loading has also been reported earlier. ,, …”

“…On the other hand, there are several inorganic filler materials (like PZT, ZnO, BaTiO 3 , BiFeO 3 , (KNa)­NbO 3 , etc. ), − which can be incorporated into the PVDF matrix for the desired performance enhancement. Other than the piezoelectric performance, a filler with specific functionality can introduce that property into PVDF-based composites too.…”

“…It has been found that different oxide-based fillers have been very widely used in the PVDF matrix for the desired performance enhancement. Due to their superior functional and electronic properties, different piezoelectric oxides, , complex magnetic oxides, − and oxide-based multiferroic composites , can be very useful in this purpose. Here, in the present work, comparatively less-explored ZnSnO 3 has been used as the filler material in P­(VDF-TrFE) matrix due to various causes.…”
