| titleOfInvention | Colorimetric gas sensors with one dimensional core(polymer)-shell(color change dye/polymer) nanofiber membrane and manufacturing method thereof |
| abstract | The present invention relates to a gas-indicating core (polymer) -shell (color-changing dye material / polymer) nanofiber membrane material in which a color-changing dye material which changes color by reacting with a specific gas molecule is bonded to the shell and the outer surface of the core- A color change sensor and a manufacturing method thereof. Specifically, a polymer electrospinning solution (first polymer) located in the core and a color change dye material / polymer composite electrospinning solution (second polymer) located in the shell are prepared, and a core-shell Characterized in that the color change dye material is selectively bound to the shell and outer surface of the nanofiber. These one-dimensional nanofibers provide more pores to allow specific gas molecules to diffuse into the membrane sensor, and can greatly broaden the area of the color change dye material exposed to air. The present invention can mass-produce nanofiber membrane color change sensors using dual nozzle electrospinning, which is relatively inexpensive to manufacture. In addition, core (polymer) -shell (chromatic dye / polymer) nanofiber membranes provide higher surface area and porosity than conventional gas sensing test papers, so even if exposed to a specific gas concentration below 1 pm, Color change occurs within a predetermined range. 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, and C 6 H 5 CH 3 ) contained in human exhalation can be detected and used as a healthcare product. |
