▎ 摘　　要

NOVELTY - Graphene coated nonwoven fabric is obtained by adding adding 10 pts. wt. graphite oxide to aqueous solution, dissolving in 200-500 pts. wt. water. The 5-10 pts. wt. sodium hydroxide, potassium hydroxide, and ammonium hydroxide are added followed by stirring at temperature of 80-100 degrees C. The first solution is produced by adding 5-10 pts. wt. sodium hydroxide, potassium hydroxide, ammonium hydroxide solution, and 5-10 pts. wt. benzoic acid. The second solution includes aromatic carboxylic acids includes salicylic acid and phthalic acid and maintained for 1-2 hours. The graphene base solution comprises graphene binding solution which includes aliphatic carboxylic acid and sprayed on the non-woven fabric to corona treatment to form graphene coated nonwoven fabric. The graphene binding solution is mixed with the first solution and second solution and maintained at 80-100 degrees C for 1-2 hours. USE - Graphene coated nonwoven fabric. ADVANTAGE - The graphene coated nonwoven fabric has excellent filtration effect.
