文摘

P3HT-SnO2 composite gas sensors were fabricated via a new in-situ surface modification route. P3HT-SnO2 composite gas sensors exhibited higher sensor response and excellent selectivity for detecting NO2 of few ppm. The synergetic effect between P3HT and SnO2 greatly improved the performance of composite gas sensors.
