摘要近年来，碳纳米技术的研究越来越活跃。因其优异的电学、力学、热学和光学性能，受到了人们的广泛关注，并逐渐成为材料研究领域的研究热点之一。在众多的碳纳米材料中，石墨烯是主要的研究目标。本文中我们通过化学气相沉积的方法来制备石墨烯，通过扫描电子显微镜和拉曼光谱分析仪等设备分析其形貌、结晶性。结果表明化学气相沉积方法制备碳纳米材料过程中温度是一个重要因素。化学气相沉积(CVD)法是近年来发展起来的制备石墨烯的新方法,具有产物质量高、生长面积大等优点,逐渐成为制备高质量石墨烯的主要方法。通过简要分析石墨烯的几种主要制备方法的原理和特点,重点从结构控制、质量提高以及大面积生长等方面评述了CVD法制备石墨烯及其转移技术的研究进展,并展望了未来CVD法制备石墨烯的可能发展方向,如大面积单晶石墨。关键词：化学气相沉积；石墨烯；扫描电子显微镜；拉曼光谱;转移AbstractInrecentyears,carbonnanotechnologyresearchmoreandmoreactive.Becauseoftheirexcellentelectrical,mechanical,thermalandopticalproperties,hasreceivedthewidespreadattention,andgraduallybecomeoneofresearchhotspotsinthefieldofmaterialsresearch.Innumerouscarbonnanotubeandgrapheneisthemainresearchtargets.Inthisarticlewethroughchemicalvapordepositionmethodtothepreparationofgraphene,byscanningelectricmicroscopeandRamanspectrumanalyzerandotherequipmentanalysisofthemorphology,crystalline.Theresultsshowthatchemicalvapordepositionmethodofpreparationofcarbonnanomaterialsisanimportantfactorintheprocessoftemperature.Chemicalvapordeposition(CVD)methodisdevelopedinrecentyears,anewmethodofpreparationofgraphene,hastheadvantagesofproductqualityishigh,thebiggrowtharea,hasgraduallybecomethemainmethodofpreparationofhighqualitygraphene.Throughabriefanalysisofgraphene,theprinciplesandcharacteristicsofseveralmainpreparationmethods,structureoffocusfromcontrol,qualityimprovementandgrowthoflargeareainCVDmethodwerereviewedtheresearchprogressofgrapheneanditstransfertechnology,andprospectsthepossibledevelopingdirectionoffutureCVDpreparationofgraphene,suchaslargeareaofsinglecrystalgraphite.Keywords:Chemicalvapordeposition;Graphene.Scanningelectronmicroscope(sem);Ramanspectroscopy;transfer目录摘要................................................................................................................................................IAbstract.........................................................................................................................................II第1章绪论.....................................................................................................................................11.1课题的目的、意义...............................................................................................................11.1.1课题的目的....................................................................................................................11.1.2课题的意义....................................................................................................................11.2课题背景...............................................................................................................................11.2.1课题背景........................................................................................................................11.3文献综述...............................................................................................................................11.3.1材料...........................................................
