PAM/MXene复合水凝胶基摩擦纳米发电机在包装运输中的应用

Applications of PAM/MXene Composite Hydrogel-Based Triboelectric Nanogenerators in Packaging Transportation

为监测包装件在运输过程中的振动情况,将MXene作为导电填料添加到聚丙烯酰胺(PAM)水凝胶中,并使用硅橡胶(Ecoflex)进行封装后组装成H-TENGs。通过扫描电子显微镜(SEM)和傅里叶红外光谱(FTIR)进行形貌检测的结果表明,MXene被成功引入到水凝胶体系中。组装的H-TENGs在测试中能够成功监测到频率为1~3 Hz的振动,并且在包装跌落实验中能够分辨出0.5~2.0 m的跌落高度。这种新型的H-TENGs在运输包装中具有良好的应用潜力。

MXene as a conductive filler was added into polyacrylamide(PAM)hydrogel,which was then assembled into H-TENGs after encapsulation with Ecoflex to monitor the vibration of the package during transportation.Scanning electron microscopy(SEM)and Fourier transform infrared spectroscopy(FTIR)results demonstrated that MXene was successfully loaded into the PAM hydrogel.The assembled H-TENGs was capable of monitoring the vibrations of the package at frequencies of 1~3 Hz during the vibration test,and was able to identify drop heights of 0.5~2.0 m during the package falling test.This kind of H-TENGs has great potential for applications in packages transportation.
