▎ 摘 要
NOVELTY - Transparent antistatic film (1) comprises: a substrate (10), at least comprising a first surface (11); and a transparent graphene coating (20), disposed on the first surface of the substrate, having a surface resistance less than 1012 ohm/square and a visible transmittance greater than 70% at 550 nm, and comprising many surface modified graphene nanosheets (21) and a carrier resin, where the surface modified graphene nanosheets are uniformly dispersed in the carrier resin. USE - The transparent antistatic film is useful in electronic devices which are sensitive to electrostatic or electromagnetic. ADVANTAGE - The transparent antistatic film: prevents various risks of electrostatic breakdown; has a function of electromagnetic wave shielding; keeps original transmittance of the substrate; has a very excellent antistatic performance; exhibits enhanced the static dissipation performance depending on an increased amount of the surface modified graphene nanosheets; and simultaneously has adjustable antistatic and transparent properties. DESCRIPTION OF DRAWING(S) - The figure shows a schematic diagrammatic view of transparent antistatic film.
