| 摘 要： | 采用原位聚合方法制备聚(2-甲氧基-5-辛氧基)对苯乙炔(PMOCOPV)/二氧化钛(TiO2)纳米复合材料。利用扫描电镜(SEM)、透射电镜(TEM)、X射线衍射(XRD)和热失重(TG)等方法对纳米复合材料的微观结构与性能进行表征。结果显示,纳米复合材料中TiO2并不是简单地与PMOCOPV分子共混,而是被PMOCOPV分子链缠绕包裹;纳米复合材料为分散均匀的球形微粒,粒径尺寸为60nm～80nm左右;同PMOCOPV相比,纳米复合材料结晶性随着TiO2含量增加而增强,且热稳定性提高。

| Abstract: | Poly(2-methoxy-5-octoxy)-p-phenylene vinylene(PMOCOPV)/titanium dioxide(TiO2)nanocomposites with different contents of TiO2 nanoparticles were prepared by in-stiu polymerization and their microcosmic structure and properties were characterized by scanning electron microscope(SEM),tunneling electron microscope(TEM),X-ray diffraction(XRD)and thermogravimetry(TG).The results show that TiO2 nanoparticles are not blended with PMOCOPV simply but encapsulate by PMOCOPV.The nanocomposites are spheric particles that... |
