▎ 摘　　要

NOVELTY - Method of coating substrate involves mixing aqueous polymer dispersion comprising polymer having glass transition temperature (a) of less than 0 degrees C and aqueous graphene dispersion, and coating mixture on surface of a substrate and drying at temperature which is more than the temperature of glass transition temperature (a). The content of graphene is 0.01-10 pts. wt. with respect to polymer. USE - Method of coating substrate e.g. metal product, glass product, porcelain product, paper product, paperboard, plastic product, concrete and timber. ADVANTAGE - The method efficiently provides coated substrate with excellent mechanical properties. DETAILED DESCRIPTION - INDEPENDENT CLAIMS are included for the following: (1) coated substrate; and (2) use of aqueous polymer dispersion for preparing adhesive and coating material.
