In this study, synthesis of fluoroalkyl end-capped oligomers/inorganic polymer hybrids have been studied in detail from the viewpoints of the development of new fluorinated functional nanomaterials.In 2004,it was found that fluoroalkyl end-capped acrylic acid oligomer-encapsulated magnetic nanoparticles were prepared by the coprecipitation of aqueous ferric and ferrous ions in the presence of the corresponding oligomers under alkaline conditions. In addition, nanometer size-controlled gold particles were prepared under mild conditions by reducing the corresponding metal precursor in the presence of self-assembled molecular aggregates formed by fluoroalkyl end-capped oligomers.In 2005,it was found that the stable gold nanoparticles protected by these fluorinated molecular aggregates were applied to the dispersion above the poly(methyl methacrylate) film surface. Furthermore, fluoroalkyl end-capped oligomer-encapsulated magnetic nanoparticles were also applied to the dispersion of magnetic particles on the poly(methyl methacrylate) film surface to exhibit not only the surface active property imparted by fluorine but also magnetic behavior toward a permanent magnet. In particular, we have succeeded in the development of the fluorinated functional polymer hybrids possessing a biological property such as an antibacterial activity. Therefore, these fluorinated organic/inorganic polymer hybrids have high potential for new fluorinated functional nanomaterials.

本研究从开发新型含氟功能纳米材料的角度对氟烷基封端低聚物/无机聚合物杂化物的合成进行了详细研究。2004年，发现通过水性铁离子和亚铁离子共沉淀法制备了氟烷基封端丙烯酸低聚物包裹的磁性纳米粒子。 在碱性条件下生成相应的低聚物。此外，在氟烷基封端低聚物形成的自组装分子聚集体存在下，通过还原相应的金属前体，在温和条件下制备了纳米尺寸控制的金颗粒。2005年，人们发现将这些氟化分子聚集体保护的稳定的金纳米颗粒应用于聚甲基丙烯酸甲酯薄膜表面上方的分散体中。此外，还将氟烷基封端低聚物封装的磁性纳米颗粒应用于聚甲基丙烯酸甲酯薄膜表面上的磁性颗粒分散体，不仅表现出氟赋予的表面活性特性，而且表现出对永磁体的磁性行为。特别是，我们成功开发了具有抗菌活性等生物特性的氟化功能聚合物杂化物。因此，这些氟化有机/无机聚合物杂化物具有作为新型氟化功能纳米材料的巨大潜力。
