| 摘 要： | 采用非晶态聚甲基丙烯酸甲酯（PMMA）与结晶型聚偏氟乙烯（PVDF）熔融共混．制备了PVDF／PMMA复合材料。利用Hilderbrand的溶解参数原则、差示扫描量热法（DSC）和微分热重法（DTG）分析了PVDFfPMMA共混物的相容性和热性能，并用X射线衍射仪和扫描电子显微镜研究了共混片材的微观结构与形态。结果表明，PMMA与PVDF具有良好的相容性，PMMA的加入降低了PVDF的结晶能力和熔融温度；随着PMMA的含量增加，PVDF的分解温度降低；PVDF的结晶度降低，球晶尺寸增大。另外，PMMA的引入改变了PVDF的结晶结构，导致了β相形成。

| Abstract: | The authors synthesized a kind of composite material from amorphous polymethyl methacrylate (PMMA) and crystalline polyvinylidene fluoride (PVDF) with melt blending process.The compatibility and thermal properties of the PMMA/PVDF blend were analyzed in terms of Hilderbrand dissolution parameter principle and by differential scanning calorimetry (DSC) and derivative thermogravimetry(DTG).The microstructure and morphology of the PMMA/PMMA sheet were studied with scanning electron microscopy(SEM) and X-ray di... |
