【摘要】

：

由于单氟磷酸钠的水溶性较大，使用时常用溶液的方式从建筑外表面渗透进入混凝土内部，其阻锈机理也是利用MFP与钢筋混凝土中的钙或是铁离子反应生成沉淀物，阻止钢筋锈蚀的进一步进行。本论文采用不同用量MFP与两种高聚物聚苯乙烯和聚乙烯共混挤出制备阻锈颗粒，可改变MFP传统渗透的方式为直接掺入混凝土中。熔融共混挤出制备阻锈颗粒可避免微胶囊阻锈剂的复杂制备工艺，提高制备效率，且可方便改变壁材来调节MFP释放速

配体交换法制备磁性荧光微粒

本论文利用共沉淀法制备出Fe304并用油酸进行改性:将3-(甲基丙烯酞氧)丙基三甲氧基硅烷、聚乙二醇甲基丙烯酸酯以及荧光可聚合配合物Eu(AA)3Phen共聚制备出两亲聚合物，两者在N2气环境和室温下反应，通过配体交换法使两亲聚合物替换掉Fe304表面油酸，产物(PMNPs)通过磁分离等方式纯化。测试结果表明，配体交换法有效的改性了单颗粒的磁性纳米粒子，所制备的微粒粒径较为均一，平均粒径仅为45n
