The patent US12037741B2 describes a textile article that incorporates a unique pattern composed of graphene. This pattern features both full portions, where graphene is present, and empty portions, where it is absent, with the full portions occupying between 10% to 70% of the surface area. The graphene used consists of nanoplatelets, with at least 90% having a lateral size ranging from 50 nm to 50,000 nm and a thickness between 0.34 nm and 50 nm. The carbon to oxygen (C/O) ratio of these nanoplatelets is specified to be greater than or equal to 100:1. The amount of graphene distributed across the textile is between 0.2 to 5 g/m², and the article may include a polymeric binder to enhance its properties.

Additionally, the patent outlines a method for preparing this textile article, which involves applying a composition that includes a polymeric binder, a compatibilizing solvent, a thickener, and graphene nanoplatelets. The application process is designed to create a specific pattern on the textile, ensuring that the full portions occupy a defined percentage of the surface area. The method also includes a heating step to solidify the composition, with temperatures ranging from 120°C to 180°C for a duration of 1 to 10 minutes. The textile article can be used in various clothing items, including shirts, jackets, and socks, and is characterized by its electrical conductivity, measured in surface resistivity, which falls within specified ranges according to the JIS K 7194 standard.
