| titleOfInvention | Colorimetric gas sensors with hydrohpilic particles and color change dye anchored one dimensional nanofiber membrane and manufacturing method thereof |
| abstract | The present invention relates to a gas-indicating polymer nanofiber membrane color-change sensor and a method of manufacturing the same, wherein particles having hydrophilicity and a color-changing dye material, which changes color by reacting with specific gas molecules, are bound to nanofibers uniformly. Specifically, the electrospinning solution is prepared by mixing the hydrophilic particles and the color change dye material in the polymer solution, and the electrospinning solution is mixed with the color change dye material of fine crystals through the high temperature stirring process and the quenching process And the resulting electrospinning solution is electrospun, so that the hydrophilic particles and the color change dye material are firmly adhered to the nanofibers. In addition, the hydrophilic particles adsorb moisture in the air to increase the reactivity between the gas molecules and the color change dye material, thereby greatly increasing the color change sensitivity. The present invention can mass-produce nanofiber membrane color change sensors using electrospinning, which is relatively inexpensive to manufacture. Complex polymer nanofiber membranes with hydrophilic particles and color change dye materials provide higher surface area and porosity than conventional gas sensing test papers, so that even when exposed to a specific gas concentration below 1 ppm, . These high-performance color-change gas sensors are environmentally harmful gases (H 2 S, SO x , NO x , CO x ) and biological indicator gases (CH 3 COCH 3 , C 2 H 5 OH, C 6 H 5 CH 3 ) contained in human exhalation |
