摘要
通过原位本体聚合法制备了一系列透明的APhen-CdS纳米微粒/聚合物复合材料.透射电镜(TEM)测试显示,APhen-CdS微粒均匀的分散在聚合物中,微粒直径仍保持2-5nm,荧光光谱(PL)表明,APhen-CdS微粒在聚合物中仍然保持其光学性质,而且当聚合物材料中加入甲基丙烯酸(MAA),甲基丙烯酸环氧丙酯(GMA)作为共聚单体时,聚合物材料的发射峰发生蓝移,且发光强度也增强,这可能是由于APhen-CdS微粒与聚合物单体发生反应或相互作用.热重分析(TGA)表明,聚合物复合材料具有良好的热力学稳定性.
A series of transparent APhen-CdS NPs/nanocomposites were synthesized by in-situ bulk polymerization. TEM images showed that the APhen-CdS nanoparticles （NPs） were uniformly dispersed in nanocomposites with a mean diameter of 2--5nm. The APhen-CdS NPs still retained their fluorescent properties in the polymer matrix. It was found that when the methacrylic acid （MAA） and glycidylmethacrylate （GMA） as the comonomers were introduced into the polymer matrix,the emission peaks of the nanocomposites had a blue shift and the fluorescent intensities also increased. This may occur due to the interaction between APhen-CdS NPs and the polymer matrices. TGA curves indicated that the nanocomposites had an excellent thermal stability.
