A novel piezoelectric paper based on antimony sulfoiodide (SbSI) nanowires is reported. The composite of tough sonochemically produced SbSI (with lateral dimensions 10–100 nm and length up to several micrometers) with very flexible cellulose leads applicable, elastic material suitable use in fabrication of, for example, nanogenerators. For mechanical energy harvesting, cellulose/SbSI nanocomposite may be used. Due its high values electromechanical coefficient (k33 = 0.9) (d33 1 × 10−9 C/N),...
Environmental monitoring systems enable the collection of information about various environmental parameters, pollution levels, and presence hazards affecting human marine life. Highly sensitive, stable, low-power-consuming sensors are vital for such operations. Nanomaterials with different surface morphologies can play a role in multiple applications, as gas sensors, photocatalysts, erosion monitoring, or fine dust sensor. Zinc oxide (ZnO) tetrapod, particular, shows 3D that exhibit...
In this manuscript, a new fabrication technology for epoxy resin/antimony sulpho-iodide (SbSI) nanowire composites is presented. SbSI nanowires, with lateral dimensions of 10 nm to 100 and lengths up several micrometres, have been synthesised using ultrasound irradiation. The prepared nanowires bound resin in mass ratio 1:4, then irradiation has used again homogenization the mixture. fabricated resin/SbSI composites, due piezoelectric properties (electromechanical coefficient k33 = 0.9, dV...
Abstract Growing demand for electric energy in newly developed electronic systems causes increasing interest research on piezoelectric nanogenerators (PENGs). Design and fabrication of such devices is challenging, considering cost materials used their construction. This the main reason why intensive has begun 0‐3 composites with properties. One most promising constituent are polymers, due to low easy processing. Herein, we present fabricated wearable PENG good impact vibration conversion...
Abstract In this paper a novel method of SbSI single crystals fabrication is presented. sonochemically prepared gel used as an intermediate product in vapour growth process. The main advantages the presented technique are follows. First, source material has lower temperature sublimation and allows to avoid explosions during synthesis (the sonochemical free any explosion hazard). Second, but not least, grown have smaller ratio longitudinal lateral dimensions. cross sections relatively large...
This paper shows a piezoelectric response from an innovative sensor obtained by casting epoxy-SbSI (antimony sulfoiodide) nanowires nanocomposite to grid structure printed using fuse deposition modeling (FDM) method. The is shown be support for the nanocomposite. applied design approach prospectively enables formation of sensors with wide spectrum shapes and applicability. voltage signal as result effect reached 1.5V 0.5V under maximum static stress 8.5 MPa dynamic 22.3 kPa, respectively....
In this paper, the performance of epoxy/SbSI nanocomposite under tensile stress was investigated. X-ray diffraction studies show main mode has shear nature in case elastic deformation, while a combination and during plastic deformation caused lattice SbSI shift sulfur atoms along c axis unit cell. Apart from that, piezoelectric signals were recorded tests. Epoxy/SbSI responded to applied by generating current with relatively high value. The measured peak-to-peak is (Ip-p = 1 pA) comparison...
