“…It has many outstanding properties, including high thermal conductivity, mechanical rigidity, and good chemical resistance. − Furthermore, BN nanosheet, which has central symmetry due to its atoms, is being actively researched as a new piezoelectric material because its central symmetry is broken by external forces, resulting in piezoelectricity. − However, inorganic BT and BN exist in zero-dimensional (0D) and two-dimensional (2D) particles with low toughness, respectively, which makes them difficult to use alone for flexible and or wearable piezoelectric devices . To address this, they should be combined with easily processable polymeric matrices, including poly(vinylidene fluoride) (PVDF), polyurethane (PU), polydimethylsiloxane (PDMS), etc. , …”

We investigate the microstructure and deformation mode-sensitive piezoelectric performance of waterborne polyurethane (WPU)-based hybrid nanocomposite films reinforced with 0-dimensional barium titanate (BT) nanoparticles and 2-dimensional boron nitride (BN) nanosheets. To this end, anionic WPUbased hybrid nanocomposites, including 40 wt % hybrid fillers composed of different BT/BN contents (BN content of 0−10 wt %), are fabricated via a sequential process of aqueous dispersion casting, hot pressing, and electric poling. The BT nanoparticles are characterized as agglomerated in the WPU matrix, while BN nanosheets are randomly distributed. The dielectric constant and loss values are highest for the nanocomposite film with only 40 wt % BT loading, and they decrease with the increment of the relative BN content in 40 wt % hybrid fillers. Under the compression deformation mode, the piezoelectric outputs (voltage, current, and power) of the nanocomposite films decrease with the increment in the relative BN content of the hybrid fillers. On the other hand, under the bending deformation mode, the piezoelectric outputs increased with the increment in the BN loading in the hybrid fillers up to 7 wt %. This deformation mode-sensitive piezoelectric performance of the hybrid nanocomposite films is associated with the difference in dipole moment directions between BT nanoparticles and BN nanosheets. In addition, the WPU/BT/BN-based hybrid nanocomposite films exhibit piezoelectric sensing performance depending on the compressive stress (5−30 kPa) as well as the bending curvature radius (3−15 mm).

“…In insulating composites, polymers are considered to be the ideal matrix material because of their good electrical insulation properties, low cost, and excellent processability. Commonly used polymers include epoxy resins, phenolic resins (PF), polyether ether ketone (PEEK), polyphenylene sulfide (PPS), and polyetherimide (PEI), with resin materials being the most widely used [2,3]. However, resin materials have poor temperature resistance, low thermal conductivity, and weak mechanical properties, and, thus, cannot meet the demands of applications at high operating temperatures.…”

“…Harvesting excess system vibrations and turning them into energy is an attractive principle that has been intensively studied in the field of piezoelectric energy (re-)generation [1] , [2] , [3] , [4] . The emerging field of piezocatalysis takes this concept one step further and directly utilises vibrations to catalyse various chemical reactions.…”
