Nuremberg, (Alemania), 2012.In this work, a new optical device based on silver loaded electrospun nanofibers (ENFs) for measuring Relative Humidity is proposed. Fiber mats composed of poly(acrylic acid) and β-cyclodextrin were deposited onto an optical fiber core by electrospinning. Afterwards the ENFs were submitted to a thermal curing. Then, the ENFs were loaded with Ag nanoparticles (Ag NPs) synthesized using a Ag+ loading step and a further reduction step with dimethylamine borane (DMAB). Several load/reduction cycles were performed. Ag NPs enhance significantly the optical response of the polymer-only fiber mats. The Ag NPs loaded ENF sensor was tested using controlled variations of Relative Humidity (RH). The results showed a very fast response of the absorbance spectra enabling high performance applications such as human breathing monitoring.application/pdfengOptical fiber sensingElecrospinningHumiditySilver nanoparticlesinfo:eu-repo/semantics/conferenceObjectinfo:eu-repo/semantics/openAccessAcceso abierto / Sarbide irekia
