核壳结构有机/无机复合微球的制备与应用进展

Preparation and Application Advance of Core-Shell Organic/Inorganic Composite Microspheres

根据核、壳的组成,核壳结构有机/无机复合微球可以分为2类:A类是核为无机材料,壳为高分子材料的核壳式结构;B类是核为高分子材料,无机材料作为壳层的核壳式结构。综述了B类复合微球的研究进展,详细讨论了复合微球的制备方法,如原位化学沉积法、溶胶-凝胶法、化学镀法、自组装法,并对各种制备方法的优缺点进行了总结,介绍了复合微球在轻质雷达吸波材料、光子晶体、生物医药载体材料、化妆品等领域的应用。最后指出了该研究领域未来的发展方向。

Based on the composition of core and shell, core-shell organic/inorganic composite microspheres can be divided into two species. The composite microspheres possess macromolecular shell and inorganic core are titled as microspheres A, and those possess inorganic shell and macromolecular core are titled as micropheres B. The recent research progresses of microsphere B are reviewed in this paper. Several preparations approaches, such as in-situ chemical deposition, sol-gel method, electroless plating and self-assembly are presented in detail, and the advantage and disadvantage corresponding to each method are summarized. In addition, applications of these composite microspheres for light mass radar absorbing material, photonic crystals, biomedical carrier and cosmetic are introduced. Finally, the development trend and prospects of these composite microspheres are proposed.
