用户论文(2005)：荧光素三元共聚纳米微粒的合成及其荧光性质

【中文摘要】 目的:合成苯乙烯(St)、丙烯酰胺(AAm)和丙烯 酸(AA)三元共聚荧光高分子微球并对其性质进行研究. 方法:采用无皂乳液聚合法合成三元共聚荧光微球.利用正 交设计表L18(37)考察温度、搅拌速度、pH值、离子强度和反 应时间对聚合物性能的影响.用透射电镜和原子力显微镜 观察微球形态及其分布,并测定其粒径大小.用荧光分光光 度计测定荧光性质.结果:在75℃,搅拌速度300r/min, pH7.5,0.5gNaCl,反应4h时合成的胶乳呈单分散性,稳 定性高,荧光性能好,其荧光最大激发波长为551.7nm,发射 波长为554.2nm.当pH值为6.0时荧光微球的荧光... 【英文摘要】 AIM: To synthesize the ternary copolymer microspheres Styrene-Acrylamide-Acrylic acid (St-Aam-AA) including fluorescein and to study their properties.METHODS: The ternary fluorescent copolymer microspheres were synthesized by means of emulsifier-free emulsion polymerization.The effects of different factors on property of polymer were evaluated by using orthogonal-designing table L 18 (3 7).Five factors with three levels were considered in the experiment,namely,temperature,agitating rate,the value of p...
