Title of the thesis:Gas Sensor Based on Carbon-Polymer Composites
Summary:This work deals with a study of novel materials for solid-state gas sensors based on polyaniline, and its composites with carbon nanotubes. It brings the state-of the art in the field of solid-state gas sensors.. Samples of the above mentioned materials were prepared on gold inter-digitated electrodes fabricated on oxidized Si wafers. Measurement stand for characterization of gas sensitive chemiresistors was designed together with automated measurement system in LabView environment. The concept of the solution was put in practice and is presented together with the data measured in the experiments. Acquired electrical characteristics are discussed taking into account morphological data obtained from scanning electron microscope. Some interesting properties of these materials were found e.g., low temperature coefficient of resistance and space charge limited conductivity. In comparison with common metaloxide sensors, our polymer nanocomposite sensors do not reach the sensitivity of the former, but, on the other side, the polymer sensors can operate at room temperature.Finally, suggestions for future improvements of the resistive sensors based on nanocomposites carbon/polymer are presented.
Key words:gas sensor, polyaniline, carbon nanotubes, nanocomposite
