Description
Technical field
The present invention relates to a kind of conduction reference electrode material, especially relate to a kind of hydrophilic nano micron-sized microphase half-detached conductive Ag/AgCl reference electrode pastes and preparation method thereof, be applicable to silk screen printing or drum-type print production technical field.
Background technology
The reference electrode that silver and silver chlorate (Ag/AgCl) are formed is to be extensive use of electrode the most, and the reference electrode of the most common pH electrode interior is exactly Ag/AgCl.Generally use many fields (as seawater corrosion prevention erosion device) of electrochemical method test the physical-chemical parameters and all can use reference electrode.In recent years, use silk screen printing, cylinder prints continuously and alternate manner (as the slot coated formula) is widely used, and has played the high speed development that promotes this field at extensive and ultra-large production microelectrode especially.Conductive silver and silver chlorate (Ag/AgCl) printing-ink has become the miniaturized solid-state reference electrode preferred material.Reference electrode Ag/AgCl complicated traditional electrochemistry is used uses screen printing technique production, has changed classical traditional reference electrode Ag/AgCl fully, complex manufacturing technology.These new things, having promoted according to electrochemistry is developing rapidly of principle biology sensor, and for example medical Ag/AgCl reference electrode is to be widely used in electrocardiogram, electroencephalogram (EEG), muscle/electro-neurogram etc., this reference electrode annual consumption arrives over ten billion tens.At present electrically conductive ink comprises that the production of silver and silver chlorate (Ag/AgCl) printing ink uses the carrier of macromolecular material as electric conducting material mostly, be that conducting metal is suspended in the macromolecular material as decentralized photo, be printed onto after the base material in addition dried, just obtained solid-state printing conductive type Ag/AgCl reference electrode.In view of conduction and printing precision and fineness require more and more higher, also high to the macromolecular material quality requirement, technological difficulties are, macromolecular material itself and metal are two materials that performance is just the opposite, one is conductor, and another is an insulator, and moreover, two kinds of materials are released states in the microcosmic phase forever.Adopt macromolecular material method excessive and the raising viscosity to solve problem of phase separation at present.The consistency and the high conductive characteristic of metallic conductor have been destroyed like this.For consistency and the high conductive characteristic that keeps metallic conductor, must adopt the method that reduces material concentration again, like this can be because the effect of shortcoming high molecular bonding, the microcosmic phase is very inhomogeneous, can produce many holes and cavity in the product, influencing quality also influences and saves raw-material direction to the ultrafine printed circuit and develop.
Summary of the invention
The objective of the invention is for overcoming above-mentioned the deficiencies in the prior art part, a kind of hydrophilic nano micron-sized microphase half-detached conductive Ag/AgCl reference electrode pastes and preparation method thereof is provided, it includes macromolecular material, double solvents, silver and silver chlorate powder and surfactant are formed, wherein macromolecular material is two or more macromolecule composition, in double solvents, macromolecule is compatible fully, form even phase, being printed onto the base version goes up dried solid-state, form the release accurate network structure of microfacies half point, form the nanoscale hydrophilic membrane at the interface that microfacies is separated simultaneously.
Microcosmic phase half point is from macromolecular material system principle:
Compatibility between two kinds of macromolecules can be judged with solubility parameters, can use following formulae express:
