The present disclosure belongs to the technical field of coatings, and in particular relates to a graphene-modified silicon-titanium nano-polymer slurry, and a preparation method and use thereof. When the graphene-modified silicon-titanium nano-polymer slurry provided by the present disclosure is added to a polymer coating, the high resistance of graphene to gas and liquid permeation and the silicon-titanium graphene network structure can significantly increase the resistance of a formed coating layer to medium permeation; due to the corrosion resistance of graphene, titanium, and silicon nanoparticles, a formed coating layer has very high stability, is not easy to react with various media such as an acid, an alkali, and a salt, is not easily consumed to form pores, and is not easy to react with corrosive media to generate soluble salts or cathodic loose and expanded products, which ensures the long-term stability of a composition and a structure of the coating layer.

A coating composition contains silica fine particles having an average particle size of 3 nm or more and 25 nm or less, a solvent having a boiling point of 150° C. or higher and 300° C. or lower, and water. The content of the silica fine particles is 0.1 mass% or more and 5 mass% or less. The content of the solvent is 20 mass% or more and 70 mass% or less.

A composition contains silicic acid polycondensate modified with organic groups, as a coating for medicines and foodstuffs or as a component in such a coating. The organic groups are partially or wholly biodegradeable. A method for producing a product coated with the composition and a coated product are further described.

A soft conductive composition can include: a crosslinked silicone composition; and single-walled or multi-walled carbon nanotubes in the silicone composition. A neural probe or other implant can include the soft conducive composition on a least a portion of the implant body. A method of making an implant can include: selecting PDMS precursors; cross-linking the PDMS precursor to obtain an elastic modulus of about 3-9 kPa or +/−1%, 5%, 10%, 20%, or 50%; selecting the carbon nanotubes; introducing the carbon nanotubes into the crosslinked PDMS to form a soft conductive composite composition; and coating the soft conductive composite composition onto at least a portion of an implant. A method of measuring properties at a neural interface can include: providing a neural probe having a soft conductive composition; implanting the neural probe having the soft conductive composition at a neural interface; and measuring a property with the neural probe.

A method for fabricating a circuit board comprises preparing an elastomeric substrate having a roughened surface. The elastomeric substrate is stretched before an electrically conductive material is electrolessly deposited onto the roughened surface. A suitable amount of electrically conductive material is deposited onto the elastomeric substrate before the elastomeric substrate is released from its stretch.

The present invention provides one with an iron electrode employing a binder comprised of polyvinyl alcohol (PVA) binder. In one embodiment, the invention comprises an iron based electrode comprising a single layer of a conductive substrate coated on at least one side with a coating comprising an iron active material and a binder, wherein the binder is PVA. This iron based electrode is useful in alkaline rechargeable batteries, particularly as a negative electrode in a Ni—Fe battery.
