▎ 摘　　要

NOVELTY - Air purification material based on gamma-undecalactone, comprises 60-65 pts. wt. polymaleimide, 35-41 pts. wt. polyoctyl suberate, 12-15 pts. wt. slow-release fragrance, 11-20 pts. wt. modified diatomite, 2-5 pts. wt. silk protein, 1-2 pts. wt. humic acid, 1-2 pts. wt. citric acid and 2-3 pts. wt. sodium cocoyl glycinate. The slow-release fragrance comprises (i) ultrasonically dispersing graphene oxide and deionized water, adding vitamin C, stirring for 1-2 hours, heating and reacting in a water bath at 95degrees Celsius for 1 hour, centrifuging, washing and drying to obtain graphene aerogel; (ii) mixing gamma-undecalactone and absolute ethanol, adding graphene aerogel and mixing for 30-50 minutes, allowing to stand for 2-4 hours, filtering and freeze-drying. USE - Used as air purification material based on gamma-undecalactone. ADVANTAGE - The material utilizes pure gamma-undecalactone fruit, so that the material releases aroma while adsorbing organic pollutants in the air, so as to better achieve the purpose of air purification.
