摘要
本文用透射电子显微镜、电子衍射和 X—射线衍射技术研究三聚氰胺甲醛/聚乙烯醇复合物的结构。结果认为,三聚氰胺/聚乙烯醇复合物存在单晶,其晶体是由很薄的片状单晶叠加而成的,属于单斜晶系,晶胞参数为 a=0.51nm,b=1.69nm,c=0.53nm,β=59.3°。
The structure of melamine formaldehyde/poly(vinyl alcohol)(MF/PVA)composites has been studied with transmission electon microscopy,electron diffraction and X-ray diffraction techniques.The single crystals are existed in MF/PVA composites. The crystal of MF/PVA composites is monoclinic with a=0.51nm,b=1.69nm, c=0.53nm.β=9.5.
