在过氧化苯甲酰作用下,利用甲基丙烯酸十二氟庚酯与丙烯酸丁酯、甲基丙烯酸二甲氨乙酯、丙烯酸羟丙酯的溶液聚合反应合成了一种氟代聚丙烯酸酯(FBDH),用场发射扫描电镜(FESEM)、原子力显微镜(AFM)等对其结构、成膜性及膜形貌进行了研究.结果表明,在观察尺寸为50 nm、扫描范围为5 μm×5μm条件下,观察所合成的FBDH微观上会表现出一种相分离结构,在其表面有众多凸起峰状物存在.将FBDH附着固化在棉纤维织物表面,可明显改善织物的疏水效果,并使水的静态接触角达到138.5°;而用1%硅溶胶对棉纤维先进行粗糙化处理再附载FBDH,则有助于产生超疏水效果,且能使处理后织物表面的接触角达到153.6°.
