NOVELTY - Graphene molecular sieve coating comprises 50-70 pts. wt. graphene mother liquor, 20-35 pts. wt. molecular sieve, 5-15 pts. wt. filler and 3-10 pts. wt. adhesive. USE - Used as graphene molecular sieve coating. ADVANTAGE - The coating: has long service life, excellent corrosion resistance, strong adhesive force, excellent ductility and excellent processing performance; improves conductivity of the aluminum foil; and maintains excellent heat dissipation and anti-corrosion performance after processing. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for preparing graphene molecular sieve coating, comprising (i) adding dispersant into nano graphene, subjecting to ultrasonic oscillation to obtain graphene mother liquor, where the ultrasonic frequency is 10-30 kHZ, and oscillation time is 0.5-3 hours, (ii) mixing uniformly polymethacrylate, polyvinyl alcohol, diphenylmethane diisocyanate, water and ethyl acetate under stirring condition to obtain a adhesive, (iii) mixing uniformly adding silicon dioxide, bentonite, alumina, diatomite and mineral powder under stirring condition, heating to 500 degrees C and heat preservating for 1 hour to activate, cooling to normal temperature, freezing at -50 degrees C for certain hour, placing into a milling apparatus, ultrafine grinding to particles of less than 100 nm, introducing nitrogen gas grinding, then stirring uniformly to obtain a filler, and (iv) mixing uniformly the graphene mother liquor, molecular sieve, filler and adhesive to obtain final product.
