Abstract: The present invention relates to transparent antistatic films using graphene, and methods for preparing the same. The films include conductive particles comprising a single-layer or multi-layer graphene, and a binder. The films are prepared by dispersing graphene in a solvent to obtain a graphene dispersion; dissolving a curable binder to a solvent to obtain a binder solution; mixing the graphene dispersion, the binder solution and optionally an additive to obtain a coating solution; applying the coating solution onto a substrate and drying the solution to form a coated film; and curing the coated film. According to the present invention, transparent or semitransparent antistatic films having excellent permeability, abrasion resistance, scratch resistance, chemical stability and dimensional stability can be prepared. The films also have superior adhesion to substrates and applicability, and thus may be advantageously applied to rigid or flexible substrates.
