A Facile Design of Colourimetric Polyurethane Nanofibrous Sensor Containing Natural Indicator Dye for Detecting Ammonia Vapour

Chemicals and industrial gases endanger both human health and the environment. The inhalation of colourless ammonia gas (NH<sub>3</sub>) can cause organ damage or even death in humans. Colourimetric materials are becoming more popular in the search for smart textiles for both fashion and...

The inhalation of colourless ammonia gas (NH<sub>3</sub>) can cause organ damage or even death in humans. Colourimetric materials are becoming more popular in the search for smart textiles for both fashion and specific occupational applications. Colourimetric textile sensors based on indicator dyes could be very useful for detecting strong gaseous conditions and monitoring gas leaks. In this study, black carrot extract (BCE) as a natural indicator dye and polyurethane (PU) polymer were used to develop a colourimetric sensor by electrospinning.

The BCE caused a change in the morphology of the PU nanofibrous mat. To evaluate the colour shift due to NH<sub>3</sub> vapour, the BCE/PU nanofibrous mats were photographed by a camera, and software was used to obtain the quantitative colour data (CIE Lab). The BCE/PU nanofibrous exhibited a remarkable colour change from pink–red to green–blue under NH<sub>3</sub> vapour conditions with a fast response time (≤30 s).
