▎ 摘　　要

NOVELTY - Composite airgel preparation involves taking 0.001-.0l pts. wt. 0.05-0.005 N,N'- methylene bisacrylamide, 0.05-0.005 pts. wt. initiator and 0.005-0.05 pts. wt. graphene oxide. The mixture is added with deionized water. The mixture is stirred at 20 degrees C for 20 minutes. The obtained mixture is molded at 50-70 degrees C for 5-6 hours. The initiator is selected from sodium persulfate, ammonium persulfate, potassium persulfate, sodium sulfite, saturated hydrogen peroxide or azodiisobutyronitrile. The obtained mixture is dried for 12-48 hours. USE - Method for preparing composite airgel (claimed). ADVANTAGE - The method enables to prepare composite airgel efficient manner.
