摘要
开发环境友好型压电材料具有重要意义。以CO_(2)为原料替代光气及异氰酸酯,其与不同结构的二胺反应合成CO_(2)基聚脲(PU);通过静电纺丝技术制备PU纳米纤维膜;采用SEM、XRD、FT-IR、TG等仪器对PU纳米纤维膜的结构进行研究,并组装压电传感器测试压电性能。结果表明:随着二胺碳链长度的增加,PU纳米纤维膜的压电性能逐渐降低;PU-6纳米纤维膜的纤维形貌和压电性能最好,输出电压为4 V,并且具有良好的稳定性和耐用性,在智能可穿戴领域有潜在应用前景。
It is of great significance to develop environment-friendly piezoelectric materials.CO_(2)-based polyurea(PU)was synthesized by using CO_(2) as raw material instead of phosgene and isocyanate to react with different diamines.The electrospinning technology was used to prepare PU nanofiber films.The structure of PU nanofiber films was investigated by SEM,XRD,FT-IR,and TG,and the films were assembled as piezoelectric sensors to test the piezoelectric properties.The results show that with the increasing carbon chain length of diamine,the piezoelectric properties of PU nanofiber films gradually decreased.PU-6 nanofiber film has the best fiber morphology and piezoelectric property with the output voltage of 4 V.It has good stability and durability,and can be used in the field of smart wearable.
