Title:
SELECTIVE ELECTROCHEMICAL DEPOSITION METHOD FOR NANO-SCALE PRUSSIAN BLUE THIN FILM
Document Type and Number:
WIPO Patent Application WO/2019/072034
Kind Code:
A1
Abstract:
A selective electrochemical deposition method for a nano-scale Prussian blue thin film, comprising: firstly preparing a metal electrode, the metal electrode comprising a pattern of a sensor working electrode and a pattern of a sensor counter electrode; subjecting the metal electrode to surface treatment to prepare a nanoscale or micron-scale surface microstructure; insulating the pattern of the sensor working electrode from the pattern of the sensor counter electrode; performing electrochemical deposition on the pattern of the sensor working electrode, and obtaining a Prussian blue thin film on the pattern of the sensor working electrode by controlling the deposition time, so as to form the sensor working electrode; and then performing stability scanning, heating, activation treatment and cleaning to obtain the sensor working electrode having a nanoscale Prussian blue thin film. The present invention performs surface treatment on the metal electrode to prepare a nano-scale or micron-scale surface microstructure, and improves the efficiency and effect of electrochemical deposition of Prussian blue.
