【摘要】 含羧基的烷基侧链的聚芳醚酮共聚物(PCA-PEAK)作为配体合成了CdSe-聚芳醚酮复合材料。利用红外光谱、紫外-可见吸收光谱、荧光光谱、透射电镜等技术,对其结构与光谱性质等进行了表征,证明了小尺寸CdSe纳米粒子的形成。荧光光谱表征结果显示该复合材料具有较为优异的荧光性质。开发了基于结合高性能聚合物羧基官能团的一种经典制备纳米异质化物路径。更多还原

【Abstract】 Cadmium selenium(CdSe)nano-composites is prepared with carboxylic-functionalized PAEK(PCA-PAEK)as ligand.By means of Fourier transform infrared spectroscopy,ultravioletvisible(UV-vis)spectroscopy,photoluminescence(PL)spectroscopy and transmission electron microscopy,both the structure and spectrum properties of the nano-composites are characterized to verify the formation of particle sized CdSe quantum dots(QDs).The results of PL measurement show that the nano-composite presents the distinct luminescence properties,as the result,a new method to synthesize the nanohybrids based on QDs and high-performance polymers with incorporated carboxylic moiety is developed.更多还原
