| 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. |
