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 (d = 650 pC/N) and the electromechanical coefficient (k = 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.
在本文中，铁电硫碘锑（SbSI）纳米线已被用于制备用于器件制造的复合材料，该复合材料可用于能量收集和传感器。SbSI对于纳米发电机和纳米传感器是一种非常有用的材料，其中压电系数（d = 650 pC/N）和机电系数（k = 0.9）的高值至关重要。另外，纤维素和环氧树脂是这些复合材料中的基体材料，而SbSI纳米线填充基体。文中展示了由振动引起的压电响应。然后，一种含环氧树脂的复合材料已被用作构建纤维增强聚合物压电传感器的元件。首次对纤维素/SbSI和环氧树脂/SbSI纳米复合材料的压电性能进行了比较。还展示了SbSI纳米线浓度对环氧树脂/SbSI纳米复合材料以及基于它们的纤维增强聚合物性能的影响。同时也给出了在固化过程中SbSI纳米线在环氧基质中取向的结果。
