下面结合具体实施例,进一步阐述本发明。应理解,这些实施例仅用于说明本发明而不用于限制本发明的范围。下列实施例中未注明具体条件的实验方法,通常按照常规条件,或按照制造厂商所建议的条件。除非另外说明,否则百分比和份数是重量百分比和重量份数。
以下实施例中所用的实验材料和试剂如无特别说明均可从市售渠道获得。常温或室温指4℃-25℃,较佳地15-25℃。
测试方法:
XRD(X-射线粉末衍射)方法:仪器型号:Rigaku Ultima IV,靶:Cu-Kα(40kV,40mA),于室温下使用D/tex Ultra检测器进行。扫描范围在2θ区间自3°至45°,扫描速度为20°/分钟。
由包括以下的多种因素产生与这类X射线粉末衍射分析结果相关的测量差异:(a)样品制备物(例如样品高度)中的误差,(b)仪器误差,(c)校准差异,(d)操作人员误差(包括在测定峰位置时出现的误差),和(e)物质的性质(例如优选的定向误差)。校准误差和样品高度误差经常导致所有峰在相同方向中的位移。当使用平的支架时,样品高度的小差异将导致XRD峰位置的大位移。系统研究显示1mm的样品高度差异可以导致高至1°的2θ的峰位移。可以从X射线衍射图鉴定这些位移, 并且可以通过针对所述位移进行补偿(将系统校准因子用于所有峰位置值)或再校准仪器消除所述位移。如上所述,通过应用系统校准因子使峰位置一致,可校正来自不同仪器的测量误差。
TG(热重分析)方法:仪器型号:TA Q500热重分析仪,采用N2气氛,升温速度为10℃/min
DSC(差示扫描量热法)方法:仪器型号:TA Q2000,采用N2气氛,升温速度为10℃/min
