Preparation of Gas Sensors Based on Conductive Polymers in Combination with Nanofibrous Structures - part 2

Popis výsledku v původním jazyce

Conductive polymers are polymeric compounds that can behave as conductors due to the presence of conjugated double bonds. By using suitable dopants, their conductivity can be varied within a wide range. Such activated conductive polymers can significantly change their conductivity even when exposed to toxic vapors or gases and can therefore be used as a detection layer of gas sensors. Basic methods of preparation of conductive polymers from monomers are described and their morphology and microstructure are characterized. Possibilities of application of conductive polymers to comb platforms in combination with a suitable substrate and nanofibrous structures are presented. The results of sensory experiments show that gas CP based nanofibers show a much higher sensitivity and faster response to target gases than flat film-based sensors. Reversibility and low selectivity are general features of CP sensors.
