摘　　要：对氢氧化镁和氧化石墨烯进行加热,当温度达到220℃时,发生爆炸,生成了氧化镁复合石墨烯材料.X射线衍射图谱表明,爆炸反应发生后,氧化石墨烯被还原成石墨烯,爆炸所产生的温度和压力诱导氢氧化镁迅速发生分解反应,生成氧化镁纳米颗粒,并迅速负载于石墨烯纳米片上,形成石墨烯负载氧化镁纳米颗粒复合材料.利用扫描电子显微镜和透射电子显微镜对复合材料形貌的分析表明,负载于石墨烯上氧化镁颗粒的平均粒径约为50nm.When the Mg(OH)2 and graphene oxide were heated,an explosion occurs when the temperature reaches 220℃,resulting in the formation of graphene-supported MgO nanoparticle composites.The X-ray diffraction results indicated that after an explosion reaction,graphene oxide was reduced to graphene.The explosion generated a certain temperature and high pressure,which can induce the rapid decomposition reaction of Mg(OH)2,thereby generating MgO nanoparticles.Finally,MgO nanoparticles were rapidly loaded onto graphene nanosheets.The scanning electron microscope and transmission electron mucroscope results indicated that MgO particles with an average particle size of about 50 nm are loaded onto graphene.
