Abstract
One aspect relates to a method of manufacture of a composition, including providing a precursor formulation which includes at least silver chloride and an organic vehicle, wherein the precursor formulation includes agglomerates, and comminuting the precursor formulation, wherein the composition is obtained. One aspect further relates to a substrate which is at least partially coated with a coating including silver chloride, wherein the coating has an average size of agglomerates of 30 μm or less, to an electrochemical sensor including at least one of these coated substrates and a use of the composition or a wire which is coated with the composition.
Claims15
A method of manufacture of a composition, comprising:
- (i) providing a precursor formulation which includes at least silver chloride and an organic vehicle;
- wherein the precursor formulation includes agglomerates;
- (ii) comminuting the precursor formulation, wherein the composition is obtained;
- wherein at least 75% of the agglomerates in the composition have a size of 30 μm or less;
- wherein the % are based on the number of all agglomerates in the composition.
A method of manufacture of a composite including a substrate and at least one coating including silver chloride, wherein the method comprises:
- i) providing an electrically conductive substrate having a surface;
- ii) superimposing the surface of the substrate at least in part with a composition including silver chloride and an organic vehicle thereby forming a layer;
- wherein at least 75% of the agglomerates in the composition have a size or 30 μm or less;
- wherein the % are based on the number of all agglomerates in the composition;
- and
- iii) solidifying the layer.
A composite comprising a substrate and a coating, wherein the substrate is at least partially coated with a coating including silver chloride which is at least in part present as agglomerates in the coating, wherein at least 75% of the AgCl agglomerates have a size of 30 μm or less, wherein the % are based on the number of all AgCl agglomerates in the coating.
A use of a composition including at least silver chloride and an organic vehicle, wherein the composition includes agglomerates, wherein at least 75% of the agglomerates have a size of 30 μm or less for the manufacture of a composite which includes a substrate which is at least partially covered by a layer of silver chloride.
A use of a composition including at least silver chloride and an organic vehicle, wherein the composition includes agglomerates of silver chloride, wherein at least 75% of the agglomerates have a size of 30 μm or less for the manufacture of an electrochemical sensor wherein the electrochemical sensor has an improved reference capacity, electrochemical activity, improved lifetime, an at least doubled lifetime when compared with conventional AgCl electrochemical sensors.
A use of a composite including a wire coated at least partially with a coating of silver chloride wherein at least 75% of the silver chloride agglomerates in the coating have a size of 30 μm or less for the manufacture of sensors and devices to determine the blood sugar concentration with improved sensitivity, electrochemical sensors of enhanced lifetime, and/or smaller electrochemical sensor.
