技術說明

一種磁性石墨烯奈米複合物的製備方法，包含一混合步驟：將一氧化石墨烯層、一含鐵前驅物及一微波承受物置於一容器中；以及一微波步驟：對置於該容器中的該氧化石墨烯層、該含鐵前驅物及該微波承受物施以一微波輻射令該氧化石墨烯層還原為一還原態石墨烯層，且使該含鐵前驅物分解出複數個鐵奈米粒子而附著於該還原態石墨烯層的至少一表面，而形成一磁性石墨烯奈米複合物。據此，本發明藉由施予該微波輻射，於一分鐘內的時間，即製成該磁性石墨烯奈米複合物，大幅降低製備石墨烯氧化物與磁鐵礦所組成之複合材料的時間，以及簡化製作步驟。 A method for fabricating a magnetic graphene-based nanocomposite comprises a mixing step: placing a graphene oxide layer, an iron-containing precursor and a microwave-receiving material in a container; and a microwaving step: applying microwave radiation to the graphene oxide layer, the iron-containing precursor and the microwave-receiving material to reduce the graphene oxide layer into the reduced graphene oxide (RGO) layer and decompose the iron-containing precursor into a plurality of iron nanoparticles adhering to at least one surface of the RGO layer, whereby is formed a magnetic graphene-based nanocomposite. Via applying microwave radiation within one minute, a magnetic graphene-based nanocomposite can be fabricated, whereby is greatly decreased the time to fabricate a composite containing graphene oxide and magnetite. Therefore, the method has advantages of high efficiency and simple processes.
