COLORIMETRIC GAS SENSORS WITH HYDROHPILIC PARTICLES AND COLOR CHANGE DYE ANCHORED ONE DIMENSIONAL NANOFIBER MEMBRANE AND MANUFACTURING METHOD THEREOF

摘要

The present invention relates to a composite polymeric nanofiber membrane colorimetric sensor for gas indication in which hydrophilic particles and a colorimetric dye material are bonded to a one-dimensional nanofiber structure, and a production method thereof. To this end, the composite polymeric nanofiber membrane colorimetric sensor is composed of polymeric nanofibers in which hydrophilic particles inducing moisture adsorption in the air and the colorimetric dye material changing colors in reaction to specific gas molecules are bonded. In addition, the hydrophilic particles adsorb moisture in the air to increase the reactivity between the gas molecules and the colorimetric dye material, thereby greatly increasing the color change sensitivity.
