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.

PDMS 膜在设计高选择性耐湿 H2S 化学电阻器中的双功能作用

热蒸发疏水性 PDMS 膜可以显着减轻湿度干扰/中毒(在 50% RH 下近 3 个月的响应没有下降)并提高 CuCrO 2化学电阻器对腐蚀性 H 2 S 的选择性,为实际应用提供了途径(H 2 S) 化学电阻器在环境潮湿的空气气氛中。
