【摘要】 以去离子水为基液,在无任何分散剂的情况下将氧化石墨烯悬浮于水中,用超声波处理器进行超声振荡,制备出稳定无聚沉的水基氧化石墨烯纳米流体。测试了纳米流体的STEM图像,分析了其粒径分布。对纳米流体的表面Zeta电位进行了测量,并结合DLVO悬浮理论和双电层结构进行稳定性分析,阐明了氧化石墨烯纳米流体能够长期保持稳定性的机理。更多还原

【Abstract】 Graphene Oxide was suspended in deionized water without adding any dispersant.It was dispersed with an ultrasonic processor,and the graphene oxide nanofluid can be got remaining stable for a long time without gathering and sinking.The particle size distribution of graphene oxide nanofluid was obtained by analyzing through STEM.The Zeta potential was measured and the stability mechanism was analyzed by DLVO suspended theory and electric double layer structure.This thesis clarified the mechanism of the graphene oxide nanofluid’s long-term stability.更多还原
