Bifunctional role of PDMS membrane in designing humidity-tolerant HS 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 2 chemiresistor toward erosive H 2 S, offering an avenue for the practical applications o...

description 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 2 chemiresistor toward erosive H 2 S, offering an avenue for the practical applications of (H 2 S) chemiresistors in an ambient humid air atmosphere. An approach to address the humidity interference/poisoning and selectivity issue of oxide chemiresistors by conformally coating a PDMS layer.
