“…Recently, there is a growing interest in nanogenerators and nanosensors which are fabricated based on SbSI nanowires [23,[26][27][28][29][30][31]. SbSI is a semiconductor and ferroelectric material exhibits very good electromechanical (k 33 = 0.9) [32] and piezoelectric (d 33 = 650 pC/N) properties [33].…”

In this paper, ferroelectric antimony sulfoiodide (SbSI) nanowires have been used to produce composites for device fabrication, which can be used for energy harvesting and sensors. SbSI is a very useful material for nanogenerators and nanosensors in which the high values of the piezoelectric coefficient (d33 = 650 pC/N) and the electromechanical coefficient (k33 = 0.9) are essential. Alternatively, cellulose and epoxy resin were matrix materials in these composites, whereas SbSI nanowires fill the matrix. Piezoelectric response induced by vibrations has been presented. Then, a composite with an epoxy resin has been used as an element to construct a fiber-reinforced polymer piezoelectric sensor. For the first time, comparison of piezoelectric properties of cellulose/SbSI and epoxy resin/SbSI nanocomposite has been presented. The influence of concentration of SbSI nanowires for properties of epoxy resin/SbSI nanocomposite and in a fiber-reinforced polymer based on them has also been shown. Results of aligning the SbSI nanowires in the epoxy matrix during a curing process have been presented as well.

“…Recently, antimony sulfoiodide (SbSI) nanowires have been applied for ferroelectric nanogenerator operating under shock pressure (Mistewicz et al 2016). Also, electrospun polyacrylonitrite (PAN) fibers containing SbSI nanowires have been used to construct a simple PAN/SbSI piezoelectric generator (Nowak et al 2017).…”

A novel piezoelectric paper based on antimony sulfoiodide (SbSI) nanowires is reported. The composite of tough sonochemically produced SbSI nanowires (with lateral dimensions 10-100 nm and length up to several micrometers) with very flexible cellulose leads to applicable, elastic material suitable to use in fabrication of, for example, piezoelectric nanogenerators. For mechanical energy harvesting, cellulose/SbSI nanocomposite may be used. Due to its high values of electromechanical coefficient (k 33 = 0.9) and piezoelectric coefficient (d 33 = 1 9 10 -9 C/N), SbSI is a very attractive material for such devices. The preliminary investigations of a simple cellulose/SbSI nanogenerator for shock pressure (p = 3 MPa) and sound excitation (f = 175 Hz, L p = 90 dB) allowed to determine its open circuit voltage 2.5 V and 24 mV, respectively. For a load resistance equal to source impedance (Z S = 2.90(11) MX), maximum output power density (P L = 41.5 nW/cm 3 for 0.05-mm-thick sheet of this composite) of the cellulose/SbSI nanogenerator was observed. Cellulose/SbSI piezoelectric paper may also be useful to construct gas nanosensors and actuators.
