Abstract

In this paper, hybrid coating of EA and modified nano SiO2 was prepared for optical fibers. Systematic investigation especially heat performance testing, was carried on the hybrid coating. The results demonstrate that the performance of EA with 3 % nano SiO2 was the best. From SEM images and XRD analysis, it can be concluded that amorphous nano-SiO2 was even distribution in EA. The tensile property, adhesion force, pencil hardness and glass temperature of EA coating can be improved by adding nano-SiO2, while the thermal expansion coefficient was decreased. Fiber bragg grating sensors with EA/SiO2 coating and EA were embedded in composites and processed under certain temperature and pressure, respectively. Comparing these two groups of data, results showed that modified coating could obviously decrease the hysteresis of fiber bragg grating sensor signals.
