Abstract

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 CuCrO₂ chemiresistor toward erosive H₂S, offering an avenue for the practical applications of (H₂S) chemiresistors in an ambient humid air atmosphere.
