摘要
采用反相悬浮聚合法合成的P(AM-co-MAA)水凝胶为模板,用Zn(Ac)2溶胀后,加入水合肼和NaOH溶液,通过两相界面反应,使ZnO沉积于微球表面,制得P(AM-co-MAA)/ZnO有机-无机复合微球.我们考察了制备方法、超声反应时间、水合肼浓度对复合微球表面负载ZnO量的影响.通过电镜扫描(SEM)、傅立叶红外分析(FT-IR)、热重分析(TG)等方法对微球表面形貌和无机沉积物ZnO的相对含量进行了表征.结果表明,采用Zn(Ac)2浸渍微球和水合肼在超声条件下反应,得到表面出现均匀裂痕的P(AM-co-MAA)/ZnO复合微球.
P （AM-co-MAA）/ZnO composite microspheres were prepared by inter-phases reaction of Zn （Ac）2 and hydrazine hy- drate in NaOH solution using P （AM-co-MAA） microgels prepared by reverse suspension polymerization method as template. It was investigated that the concentration of the preparation method, hydrazine hydrate concentration,reaction time of ultrasonic effect on the surface morphology of the P （AM-co-MAA）/ZnO composite microspheres. The morphology and composition of the P （AM-co-MAA）/ ZnO composite microspheres were characterized by TG, SEM, FT-IR. It is indicates that of the P （AM-co-MAA）/ZnO with uniform fissure composite microspheres loaded ZnO by using Zn（Ac）2 to soak the microspheres and the hydrazine hydrate under ultrasonic.
