Concentrated dispersions of silver nanowires are used to produce different quality silver structures having a range of properties. The concentrated dispersion may have a high weight percent of silver nanowires and may be formulated as a flowable liquid or a non-flowable paste. The concentrated dispersion may remain stable without visible settling during a week, may have a non-Newtonian rheology, and may be diluted to a desired weight percent of silver nanowires without adversely affecting the uniformity of the dispersion. The concentrated dispersions may be formulated with or without polymer or prepolymer components. The concentrated dispersion may be formulated with a silver salt to modulate the dispersion of the silver nanowires and improve the conductivity of the cured silver structure formed from the dispersion. The method of forming a concentrated dispersion is set forth as a method of forming a silver structure from the dispersion.
Resumen de: MX2025008860A
The present disclosure describes methods of deagglomerating, debundling, dispersing, and functionalizing carbon nanomaterials in a medium using a process that does not damage the properties of the carbon nanomaterials. Three exemplary types of carbon nanomaterials are conductive carbon black, graphene, and carbon nanotubes (CNT), including single-wall carbon nanotubes (SWCNT). Once the carbon nanomaterials are dispersed in the medium, the resulting carbon nanomaterial dispersion can be subjected to further processing or blended with additional components to form a coating or polymer composite material suitable for molding structural components. The dispersed carbon nanomaterial can provide the resulting part or component with desirable mechanical and electrical properties such as static dissipation and conductivity.
