▎ 摘  要

NOVELTY - An electroconductive film comprises graphene nanoplatelets packed in a apollonian manner. USE - Electroconductive film for RFID tags(claimed). ADVANTAGE - The electroconductive film has high conductivity. DETAILED DESCRIPTION - INDEPENDENT CLAIMS are included for the following: a liquid composition, which comprises a two populations (A) and (B) of graphene nanoplatelets having an average size of 25% of the average size of the first population of graphene nanoplatelets, thickening agent and solvent; a textile or thermoplastic substrate onto which the liquid composition is printed; a method of printing the liquid composition onto a textile or thermoplastic substrates; and a radio frequency identification (RFID) tag, which comprises an RFID antenna formed from the film or the liquid composition.
