Preparation of OMMT/EA hybrid coating with high temperature resistance for FBG sensors

  • 摘要: 对纳米蒙脱土(OMMT)进行改性, 用改性后的蒙脱土对环氧丙烯酸酯(EA)涂层进行改性, 并对改性后的OMMT/EA涂层进行了力学性能和热性能测试。研究表明, 加入质量分数2%改性蒙脱土的OMMT/EA涂层性能最好。OMMT的加入可提高涂层的拉伸性能、附着力和硬度, 并有效提高EA涂层的玻璃化温度, 降低其线性热膨胀系数。电镜和XRD分析表明, OMMT在OMMT/EA涂层中以单层片层均匀分布。将涂有该涂层的光纤布拉格光栅(FBG)传感器埋入复合材料中, 经一定温度与压力成型后, 与涂有未改性EA涂层的FBG传感器采集到的信号进行对比, 发现改性后涂层可明显降低FBG传感器信号滞后现象。
    Abstract: Hybrid coating of epoxy acrylate(EA) and modified nano organic montmorillonite(OMMT) was prepared for optical fiber Bragg grating(FBG) sensors. Mechanical performance testing and heat performance testing were carried on the OMMT/EA hybrid coating. The results demonstrate that, the performance of OMMT/EA coating with 2% mass fraction of nano OMMT is the best. SEM photographs and XRD analysis show that thesingle-lamellar nano OMMT is even distribution in EA. The tensile property, adhesion force, pencil hardness and glass temperature of OMMT/EA coating can be improved by adding nano OMMT, while the linear thermal expansion coefficient is decreased. FBG sensors with OMMT/EA coating and EA were embedded in the composites which processed under certain temperature and pressure, respectively. Comparing two groups of data, the results show that the modified OMMT/EA coating could obviously decrease the hysteresis of FBG sensor signals.
