| 摘 要： | 香精与人们的生活有着紧密的联系，具有消毒杀菌、改善环境、使人舒适的作用。香精与热、光、空气或金属污染物反应产生氧化、聚合、脱氢和热重排而导致物理化学性质发生变化，微囊包封固化或吸附剂表面吸附可以解决这些问题。石墨烯气凝胶具有较大的比表面积、柔韧性、热和化学稳定性，是目前被广泛研究的吸附剂。介绍了石墨烯气凝胶的制备方法和吸附机制，与传统吸附剂的香精吸附效果进行了比较，展望了石墨烯气凝胶在香精吸附领域的应用前景。

| Abstract: | Essence is closely related to people''s lives, and has the effect of disinfecting and sterilizing to improve the environment and make people comfortable. In order to avoid the changes in physical and chemical properties caused by oxidation, polymerization, dehydrogenation and thermal rearrangement due to the reaction of essence with heat, light, air or metal pollutants, microencapsulation solidification and adsorbent surface adsorption can solve these problems. Graphene aerogels are currently widely studied as adsorbents because of their large specific surface area, flexibility, heat and chemical stability. The preparation methods and adsorption mechanism of graphene aerogels are introduced, and compared the essence adsorption effect with traditional adsorbents. The application prospect of graphene aerogels in the field of essence adsorption is forecasted. |
