摘要
This invention relates to the field of preparation technology of optical pH sensor by co-intercalated fluorescein and 1-heptanesulfonic acid sodium into layered double hydroxide. The sensor is composed by conductive materials and the surface LDH films by co-interacted FLU and HES. The synthesis method is: first: synthesis of LDH colloid suspension, subsequently, the FLU and HES co-intercalated LDH colloid solution was prepared following the ion-exchange method, then the thin film of FLU-HES/LDH was spreaded on the surface of the conductive material by electrophoretic deposition, and the oriental pH sensor was synthesized. The advantages of the present invention is: first, the LDH matrix provides chromophore molecules with a confined and stable environment; the novel electrophoretic deposition strategy in this work provides a method for precise control of thickness (ranging from nanometers to micrometers), and the oriental pH sensor show good pH responsive.
