Bifunctional role of PDMS membrane in designing humidity-tolerant H 2 S chemiresistors with high selectivity

A thermally evaporated hydrophobic PDMS membrane could significantly mitigate humidity interference/poisoning (without a decline in response at 50% RH for nearly 3 months) and enhance the selectivity of a CuCrO chemiresistor toward erosive H S, offering an avenue for the practical applications of (H...

Description
Summary:A thermally evaporated hydrophobic PDMS membrane could significantly mitigate humidity interference/poisoning (without a decline in response at 50% RH for nearly 3 months) and enhance the selectivity of a CuCrO chemiresistor toward erosive H S, offering an avenue for the practical applications of (H S) chemiresistors in an ambient humid air atmosphere.
