▎ 摘 要
NOVELTY - Oxygen functional groups analysis involves preparing and calibrating standard solution of 0.05-0.1M sodium hydroxide, sodium bicarbonate, sodium carbonate, 0.1M sodium ethoxide, and 0.05-0.1M hydrochloric acid. The graphene sample is tested with an alkali solution and then dried at 60-120 degrees C for 6-24 hours to prepare graphene sample reaction suspension. The prepared graphene sample reaction suspension is separated through solid-liquid phase separation and then oscillated for 24 hours. The oxygen-containing functional groups are calculated on surface of the graphene material. USE - Method for analyzing oxygen functional groups on surface of graphene material (claimed). ADVANTAGE - The method analyzes oxygen functional groups in a simple and cost-effective manner.
