以苯乙烯(St)为主要单体,对苯乙烯磺酸钠(NaSS)和可聚合稀土荧光配合物(Eu(AA)(BA)_2Phen)为功能性单体,通过微波辐射无皂乳液聚合制备了Poly(St-NaSS-Eu(AA)(BA)_2Phen)共聚物荧光乳液纳米粒子.利用红外光谱对共聚物的结构进行了证实;通过透射电子显微镜和扫描电子显微镜观察了粒子的形态、结构及大小;利用激光光散射粒度仪测试了粒子的大小及分布;结果发现所制备的共聚物荧光乳液纳米粒子呈大小均一的球形形状,粒径大小约为35 nm;采用荧光分光光度计测试,发现共聚物纳米粒子在595 nm和619 nm处出现Eu~(3+)的特征发射光谱,具有良好的荧光效果.
Styrene (St) as the main monomer, sodium styrene sulfonate (NaSS) and a polymerizable rare earth fluorescent complex (Eu (AA) (BA) _2Phen) were used as functional monomers and were emulsified by microwave irradiation Poly (St-NaSS-Eu (AA) (BA) _2Phen) fluorescent emulsion nanoparticles were prepared.The structure of the copolymer was confirmed by infrared spectroscopy.The morphology of the particles was observed by transmission electron microscopy and scanning electron microscopy, The size and distribution of the particles were measured by laser light scattering particle size analyzer. The results showed that the prepared nanoparticles were spherical in shape and size was about 35 nm. The fluorescence spectrophotometer It was found that Eu 3+ emission spectra of the copolymer nanoparticles appeared at 595 nm and 619 nm with good fluorescence.
