Title:
QUADRUPOLE CONDUCTIVITY ELECTRODE CAPABLE OF IMPROVING SEAWATER CONDUCTIVITY MEASUREMENT PRECISION, AND PREPARATION METHOD THEREFOR AND APPLICATION THEREOF
Document Type and Number:
WIPO Patent Application WO/2022/205715
Kind Code:
A1
Abstract:
A quadrupole conductivity electrode, and a preparation method therefor and the application thereof. The quadrupole conductivity electrode comprises an electrode material and a graphene layer compounded on the electrode material. By coating a surface of a quadrupole electrode of an existing sensor with nano-scale conductive material graphene, the microcosmic area of a conductive electrode is expanded, and the contact area between the conductive electrode and seawater is thus expanded, such that the polarization is reduced, bubbles attached to the surface of the electrode are reduced, the erosion of the electrode by the seawater is weakened, and the detection precision and service life of the electrode are improved. The preparation method is simple and easy, moderate in conditions and high in controllability, can be carried out on the basis of an existing quadrupole electrode material, and is more suitable for popularization and application in industry.
