Data on Chemical Sensors and Actuators Reported by Researchers at University of Liverpool (Fabrication of textile based conductometric polyaniline gas sensor)

By a News Reporter-Staff News Editor at Journal of Technology -- Research findings on Chemical Sensors and Actuators are discussed in a new report. According to news reporting originating from Suzhou, People's Republic of China, by VerticalNews correspondents, research stated, "In this work, we report the fabrication of gas sensors prepared by in situ polymerization of aniline on non-woven fabrics. It is anticipated that a thin coating of polyaniline film fabricated on porous fabric material would improve the performance of the polyaniline based gas sensor."

Our news editors obtained a quote from the research from the University of Liverpool, "The hypothesis is based on the recent improved technique that allows the fabrication of nanoparticle based polyaniline film, and the high gas permeability of the fabrics. Sensor fabrication parameters which included acidity of reaction media, precursor and reagent concentrations, and the number of modification cycle have been studied. The resulting gas sensors were found to be highly responsive to a range of volatile organic compounds (VOCs). This high sensitivity was also accompanied with fast response time (similar to 10 s). The order of sensitivity to VOCs was found to be ethanol > chloroform > toluene > acetone > ethyl acetate."

According to the news editors, the research concluded: "Further, the sensor was three orders of magnitude more sensitive to ammonia than all organic vapours tested."
