Estimating the term…
The present disclosure relates to a color change dye prepared by impregnating hollow silica with a dye having a cationic dye and an anionic dye prepared using ion pairing, a sensor for detecting gas containing the above dye and a method for preparing the same, and more specifically to, a sensor that increases sensitivity and stability by increasing the area where the dye touches the gas and protecting the dye itself, since cationic dyes and anionic dyes are ion-paired to increase humidity resistance and react only with a trace amount of acetone. and the ion-paired dyes are then impregnated into hollow silica, and a method for preparing the same.
A color change dye for detecting acetone gas, wherein the color change dye is prepared by mixing a cationic dye and an anionic dye to perform ion-paired dye and impregnating hollow silica with the ion-paired dye, and
A method of preparing a color change dye for detecting acetone gas, the method comprising:
A sensor for detecting acetone gas, the sensor comprising a color change dye for detecting acetone gas, wherein the color change dye is prepared by mixing a cationic dye and an anionic dye to perform ion-paired dye and impregnating hollow silica with the ion-paired dye, and
A method for detecting acetone gas, the method comprising:
