摘要
将采用液-液界面析出法在甲苯/叔丁醇体系中培养的二维(2D)富勒烯C_(60)片状晶体置于含2%(体积分数)间二甲苯的异丙醇中24 h,则该2D片状晶体转变成一维(1D)晶须。通过光学显微镜,扫描电子显微镜,红外光谱,拉曼光谱,X-射线衍射法对其形貌及组成、晶型进行了表征。结果表明:1D富勒烯C60晶须与2D C_(60)片状晶体具有相同的分子组成和晶型。
The two-dimensional(2 D)C_(60) flake crystals were synthesized by liquid-liquid interfacial precipitation(LLIP).The C_(60) crystal was placed in isopropanol containing 2%(volume fraction)m-xylene for 24 h,and then the 2 D crystal was transformed into one-dimensional(1 D)whiskers.The morphology,component and structure were characterized by optical microscopy(OM),scanning electron microscopy(SEM),infrared spectrometry(IR),Raman spectroscopy and X-ray diffraction(XRD),respectively.The results showed that the 1 D C_(60) whiskers have the same component and crystal structure with 2 D C_(60) crystals.
