“…The GO used in this study is produced by the vacuum filtration method described in [10]. The preparation process consists in filtering a specific concentration of GO in water solution (concentration about 0.01 mg/ml), drying the obtained GO layer with the filter, catting the required pieces, removing the filter from the pieces by acetone and rinsing them in mixed ethanol and water solution.…”

Graphene oxide (GO) thin films fabricated by the vacuum filtration method were deposited on bare tilted fiber Bragg grating for refractometry measurements. Two different layer thicknesses (100 nm and 200nm) were used to prepare the samples. The amplitude spectra of the GO-coated TFBGs (GO-TFBGs) were measured with linearly polarized light for different refractive index values of LiCl solutions (1.3333-1.3342). We show that when polarized light is used, the 200 nm GO-TFBGs achieve similar behavior as plasmonic gold-coated TFBGs (Au-TFBGs). This latter exhibits a characteristic attenuation in the amplitude spectrum when P-polarized light excites a surface plasmon resonance (SPR). This behavior suggests that GO is present as a mix of discontinuous and stratified flakes favorable for plasmon-plasmon hybridization, which can be generated for both P and/or S-polarization of the light.

“…The absorbance spectrum of an aqueous solution of GO typically peaks at 230 nm while visible and infrared radiation is not significantly absorbed. In laminated FBG sensors, scattered UV light increases the internal energy of GO and consequently locally raises the surface temperature of optical fiber [ 19 ]. Consequently, temperature changes modify stress distribution within the fiber and result in a change in Bragg’s wavelength [ 20 ].…”

Polymer–matrix composites degrade under the influence of UV radiation in the range of the 290–400 nm band. The degradation of polymer–matrix composites exposed to UV radiation is characterized by extensive aging of the epoxy matrix, resulting in deterioration of their mechanical properties. Glass fibers/epoxy resin composites were made by an out-of-autoclave method whereas a fiber optic sensor was placed between different layers of laminates. In our work, we used a fiber Bragg grating sensor covered with graphene oxide and embedded in a polymer matrix composite to monitor UV radiation intensity. Measurements of UV radiation may allow monitoring the aging process of individual components of the polymer composite. In order to estimate the number of microcracks of epoxy resin, microstructure observations were carried out using a scanning electron microscope.

“…Recently, graphene oxide (GO), the most important derivatives of graphene, is considered as a very promising material for humidity sensing. Different from the porous material structures of polymers, GO has high surface-area-to-volume ratio and strong absorption property in a wide wavelength range, and can be integrated with optical fiber for UVA and biochemical sensing [19][20][21]. More importantly, there are rich oxygen-coating groups between layers for interacting with water molecules, such as hydrophilic hydroxyl, epoxy, and carboxylic groups [1].…”

Highlights 1. An optical fiber-based humidity sensor with ultrafast response is proposed by depositing GO onto a tilted fiber grating (TFG) with large tilted angle. 2. The experimental results show sensitivities of 18.5 pm/%RH and 0.02 dB/%RH with highly linear coefficient in the dynamic range of 30%-80%RH. 3. The sensor is successfully applied to monitor human breathing cycles with different breathing frequencies. 4. The sensor also shows the properties of easy fabrication, low hysteresis, ultrafast response, and high repeatability and reliability.
