Article Synopsis
- The study examines the effectiveness of microcellular sensory polymer films for detecting mercury in water, highlighting their unique sensory behavior.
- Initially, solid acrylic polymer films were created, and sensory motifs were added to make them colorimetric.
- When foamed under specific conditions, these films showed a significant improvement in detection speed and sensitivity for mercury compared to their solid counterparts, thanks to their enhanced surface area.
Conventional nonconductive vinylic films with dispersed aniline change their color and become conductive in the presence of specific oxidant gases, namely, chlorine and hydrogen peroxide. The color change arises from the polymerization of the aniline to yield the conjugated polymer polyaniline, which at the same time renders the flexible vinylic films conductive. We present a simple and straightforward method using both colorimetric and electrical responses to detect and quantify the presence of oxidants (Cl and HO) in the air.
