Abstract
The development of sensors goes through several parameters that must be analyzed systematically, among them: the potential for rapid detection, sensitivity, selectivity, sample preparation, concentration and portability. For this, the processing of materials, which involves a sensory layer, deserves special attention so that the final performance is satisfactory. In addition to processing, the application and synthesis of new materials as a sensor element is equally important in the development of versatile devices, bringing new possibilities for systems with reliability and durability. In this sense, polymeric materials are versatile, both in terms of synthesis and processing, opening up new possibilities for sensor devices. This work presents the application of polymeric materials, ionomers and a copolymer based on fullerene, as an ammonia gas sensor produced with different processing techniques, namely: Langmuir-Schaefer, drop cast and spin-coating. The copolymer based on fullerene and poly(ethylene oxide) (PEO) was synthesized during the sandwich doctorate period at the Université de Pau et des Pays de l'Adour, France, at the Institute of Analytical Sciences and Physico-Chemistry for Environment and Materials (IPREM). The devices were characterized through the techniques of visible ultraviolet (UV-vis) spectroscopy, atomic force microscopy (AFM), DC electrical measurements and gas testing with monitoring of the electrical current as a function of the time of exposure to the ammonia gas, where it is shown that it is possible to apply the materials involved as a sensor element.
