Abstract

A new type of optical fiber pH sensors has been fabricated using the Electrostatic Self-Assembly (ESA) Method. The device is based on the co-deposition of the polymer poly(allylamine hydrochloride) and the cohrimetric pH indicator Neutral Red as the cationic monolayers, and the polymer poly(acrylic acid) that conforms the anionic monolayers. The coatings are built up monolayer by monolayer on the ends of standard communications optical fibers with a thickness of 9 nanometers per bilayer. The final structure of the coating is an homogeneous film that forms a nanoFabry-Perot interferometer. The sensing mechanism of the sensor relies on changes in the spectral response of the coating with the variations ofpH. The range of measurement goes from pH 5 to 8.
