| 초록 |
I will introduce a novel dual stimuli responsive self-reporting coatings which can detect both crack occurrence and pH variation. For crack detection, microcapsule containing tetraphenylethylene (TPE) which exhibits aggregation induced emission (AIE) effect was prepared via multi-step emulsion polymerization and dispersed in self-reporting coatings. For pH variation detection, commercial thymol blue as a pH indicator was added into the polymer matrix. The color transition of self-reporting coatings in response to acid or base solution were quantitatively investigated using a multi-angle spectrophotometer. Finally, The self-reporting coatings used in this study was applied to laboratory scale chemical reservoirs in order to verify the potential as a dual stimuli response self-reporting coating which can detect both crack in coating material and chemical spill caused by the leakage or breakage of the reservoir part. |
