摘要
通过高能球磨机球磨石墨粉制备石墨烯(Graphene)。分别使用x射线衍射仪(XRD)、扫描电子显微镜(SEM)以及马尔文激光粒度仪(Zetasizer Nano ZS)进行结构表征与分析。同时将制备得到的石墨烯与硅粉共同加入水泥中,并使用耐驰436导热仪和电液伺服压力试验机测试其导热性能和力学性能,运用Maxwell-Garnett理论简单模拟实验数值,采用SEM分析了复合材料形貌,探讨了石墨烯纳米片在水泥中的导热机理。实验结果表明:硅粉(SF)能辅助石墨烯在水泥中的分散,在水泥中形成导热通路,提高了该复合材料的导热性能,适量的石墨烯也对复合材料的力学性能有好处,但是当石墨烯掺量过大时,虽然提高了复合材料的导热性能,但其力学性能急剧下降,限制了其应用。
Using high-energy planet in which milling graphite powder to prepare graphene.The structure of graphene was then studied by X-ray diffraction(XRD),scanning electron microscopy(SEM) and Malvern laser particle size analyzer(Zetasizer Nano Zs.The graphene and silica fume were doped into cement for graphene cement-based composite whose thermal and mechanical properities were characterized with Netzsch HFM 436 and compression test machine respectively.The Mode of Maxwell-Garnett was used to simulate experimental data and the morphology was characterized with SEM.The thermal conducting mechanism of composite was also discussed.The results shows that:Silica fume(SF) facilitated graphene dispersion which formed crosslinked network and improved thermal properities of composite.The mechanical properities of composite benefit from the right amount of grapheme.When the more graphene had increased the thermal properities,a sharp drop in mechanical properities,which limit its application.
