聚合物/量子点纳米复合材料的制备

量子点具有优异的光电性能,聚合物具有性质稳定、质轻、可加工性好等优点;将聚合物和量子点复合可综合两者的优点,同时还可使量子点的稳定性得以大幅度提高。得到的聚合物/量子点纳米复合材料应用领域广;其制备方法主要有简单易操作的直接分散法、在聚合物中原位生成量子点的原位生成法、在有量子点存在的聚合场所引发有机单体聚合的原位聚合法、层-层组装法以及在量子点表面直接修饰聚合物的表面直接修饰法。本文就这些制备方法进行了概要综述,并对各种方法的特点进行了总结。

Preperation Methods of Polymer/Quantum Dots Nanocomposites

Inorganic semiconductor quantum dots (QDs) have shown excellent photoelectric properties while polymer has several advantages such as physical and chemical stability, light weight, easy processability, etc. Incorporation of QDs into a polymer matrix can integrate their advantages. At the same time, the stability of the quantum dots also can be greatly improved. Polymer/QDs nanocomposites have been widely used in many fields, the preparation methods of which mainly include direct dispersion, in-situ synthesis of QDs into polymer matrices, in-situ polymerization of organic monomers in the presence of QDs, layer-by-layer self-assembly, and direct surface modification of QDs by polymers. In this article, the preparation methods of polymer/QDs nanocomposites are briefly reviewed and the characteristics of the various methods are summarized.
