Title:
SPEEK/IL SANDWICH STRUCTURE REFERENCE ELECTRODE, PREPARATION METHOD THEREFOR, AND APPLICATION THEREOF
Document Type and Number:
WIPO Patent Application WO/2022/142775
Kind Code:
A1
Abstract:
A SPEEK/IL sandwich structure reference electrode, a preparation method therefor, and an application thereof. The end of a reference electrode body is provided with a SPEEK/IL sandwich structure. The SPEEK/IL sandwich structure comprises two layers of SPEEK/IL composite membranes and one layer of SPEEK membrane. The SPEEK membrane layer is located on the outermost layer of the SPEEK/IL sandwich structure. The SPEEK/IL organic semipermeable membrane can keep the concentration of Cl- inside the electrode constant, so as to ensure the stability of an electrode potential in a measurement process. The SPEEK/IL sandwich structure reference electrode is an all-solid-state full-reference electrode, is particularly suitable for application to a complex natural water body having chemical components due to the features of compact structure, no need of internal reference liquid, large mechanical strength and being not prone to interference, and has wide application prospects in the fields such as deep-sea detection, oil-gas exploitation, chemical manufacturing.
