Abstract
The hydrogen(H2) energy industry has continued to expand in recent years due to the
decarbonization of the global energy system and the advancement of sustainable development.
Due to hydrogen's high flammability and significant safety risks, the efficient detection of
hydrogen has become an increasingly hot issue today. In comparison to conventional inorganic
sensors, conducting polymer based sensors are less expensive, lightweight, solution-processed,
and more flexible, while maintaining high sensitivity at room temperature operation.
In this work, a new type of relatively fast and responsive conducting polymer sensors has
been demonstrated of trace H2 gas in nitrogen environment. Facilitated by a high efficiency
solution-based fabrication approach, thin film of polyaniline(PAni), polypyrrole(Ppy) and PAni
composite are fabricated. Such type of sensor ensures the detection of miniscule current changes
caused by the interaction of low concertation H2 exposure(1 ppm) at room temperature, and
exhibits a fast response and recovery times of 94 s and 83 s.
Moreover, the sensor provide good repeatability and stability in repeated tests.This
conducting polymer-based hydrogen sensor hold promise for early detection of H2 leakage in a
broad range of industries.
