本发明涉及一种有机物表面修饰的金属和金属氧化物材料及其制造方法， 主要应用于生物、 医学、 药 物、 能源、 化工、 环境等领域。
背景技术- 无机 -有机界面问题是当前科学与技术面临的挑战，无机材料与有机材料的复合可以产生新型的高性能 材料， 其关键是有效解决有机 -无机界面的问题。 例如， 在生物医学领域， 金属钛及其合金材料植入生物体 内的骨骼固定材料、 支架材料等， 其成功与否取决于表面的生物相容性问题； 在纳米技术领域， 氧化钛纳 米颗粒做为太阳能电池半导体材料、 光催化材料、 超双疏材料、 抗菌材料、 染料涂料添加剂等， 都需要对 其表面有机修饰以提高材料的性能。
现有技术解决有机-机界面问题大部分采用物理界面的方法，如各种喷涂技术，这种物理界面的结合牢 固性较差，容易脱落。一些采用化学界面解决有机-机界面问题的方法，如表面活性剂法、硅垸偶联剂法等， 主要通过配位键、 氢键、 静电作用和范德华力等弱相互作用结合， 形成的有机 -无机界面不稳定。 因此， 金 属和金属氧化物材料与有机物的有机-无机界面问题仍然是当前科学和技术面临的巨大挑战。

合成无机磁性颗粒的方法很多， 但是， 这些无机磁性颗粒不具有表面有机活性功能基团， 难以实际应 用。 现有技术解决这一问题的主要路径是采用无机磁性颗粒与有机物形成复合材料的方案， 包括和有机分 子复合形成核壳结构磁性颗粒的方法， 如表面活性剂包覆法、 硅垸化法等， 以及和聚合物复合形成磁性聚 合物颗粒的方法， 如共混包埋法、 界面沉积法、 单体聚合法等。 但是， 这些方法都存在这样或那样的缺点 和不足， 尺寸可控、 粒度分布窄、 磁性强、 表面功能基团容量高、 合成工艺简单的磁性颗粒及其合成方法 尚有待进一步探索。
