The conductive polymer not only helps minimize the binding between the sorbate material and analytes, but also helps simplify processing during device manufacturing, compared to pristine MOFs powders, which are difficult to integrate into sensors and other electronic devices.

MOFs, though promising for chemical sensing, they often suffer from non-reversible performances. We show that the sensing reversibility can be systematically improved by alloying the MOF with conductive polymers.

Unlike other NO2 gas sensors, our design is based on all-plastic components, is easy to fabricate (just a conductive ink on a piece of plastic), & can sustain long term exposure to high temperatures (>170 C). This allows us to monitor the emission directly on chimneys and pipes.

Our lab usually studies these conductive polymers for their function in aqueous media (e.g. biosensors). Here, led by Geon & Dongha, we used newly designed composites to monitor air pollutants. Our polymers, upon molecular engineering, exhibit high affinity towards NO2 gas!
