| Outline of Final Research Achievements |
Commercially available pH electrodes have fatal problem that pH response is deteriorated by the accumulation of stain easily. In order to solve this problem, we developed two types of maintenance-free pH responsive electrodes which guarantees pH response performance by maintaining a clean state. Such pH electrodes cannot be realized with commercially available pH-responsive glass electrode. As for the development of a Li-free electronically conductive glass electrode having a self-cleaning function based on anti-fouling property (hydrophobicity), we developed Fe2O3-Bi2O3-GeO2 glasses with higher contact angle with water compared with the previously reported Fe2O3-Bi2O3-B2O3 glasses. In addition, the stainless electrode sol-gel coated with transition metal oxide showed high pH sensitivity and fast pH response. This stainless electrodes with excellent processability are candidate for a disposable pH electrode.
