摘要：

A novel self-protection sensor was successfully constructed based on an interesting thermo-sensitive triblock polymer PS-PNIPAm-PS. At low temperatures (30 °C), which dramatically increased the electron transfer resistance (Rct) of the modified electrode and consequently blocked the occurrence of the redox reaction to protect the electrode from high temperatures and enhance its stability. Under optimized conditions, the proposed sensor showed a good detection range for hydroquinone (6×10−7 to 2.35×10−3 M) and a low LOD (490 nM). The sensor...
