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。
Quantum dots have excellent optoelectronic properties, the polymer has the advantages of stable properties, light weight, good workability and the like. The combination of the polymer and the quantum dots can comprehensively combine the advantages of the two while greatly improving the stability of the quantum dots improve. The obtained polymer / quantum dot nanocomposite has a wide range of application fields. The preparation method comprises the simple and easy-to-use direct dispersion method, the in-situ method of generating quantum dots in situ in a polymer, and the polymerization site with quantum dots In situ polymerization of organic monomers, layer-by-layer assembly, and surface direct modification of polymers directly on the surface of quantum dots. This article provides an overview of these preparation methods and summarizes the characteristics of the various methods.
