聚合物-纳米晶杂化材料因结合了有机和无机材料的优点而逐渐地受到了人们普遍的关注,聚合物为纳米晶的形成与生长提供了优良的环境,纳米晶的引入同样也增加和强化了聚合物的功能特性.如聚硫代氨基甲酸酯与TiO2杂化的高折射率薄膜,该薄膜不仅保持了原有的性能,而且有较高的折射率.此外,还有许多不同纳米粒子与不同聚合物的杂化体系.如聚N,N-二甲基丙烯酰胺(PDMAA)/ZnS杂化材料,聚氨酯/PbS杂化材料等.有机-无机杂化材料不仅可以制备高折射率材料,还可以用来制备高性能光致发光的体相材料.表面带负电荷的CdTe纳米晶可以通过静电相互作用从水相转移到油相,最后通过自由基聚合,得到均一分布纳米晶的体相材料,而聚合物分子反过来也可以作为控制纳米晶生长的优良介质,进而实现对纳米晶尺寸的精确控制和性能优化.在紫外光下的发光颜色可由最初引入的纳米晶的粒径大小来控制.功能性聚合物聚对亚苯基亚乙烯基(PPV)前驱体可以与CdTe纳米晶杂化用来制备纯白色发光的杂化材料,以及高表现的太阳能电池器件.
Polymer-nanocrystalline hybrid materials have gradually gained people’s attention due to the advantages of combining organic and inorganic materials. Polymers provide an excellent environment for the formation and growth of nanocrystals. The introduction of nanocrystals also increases and Which enhances the functional properties of polymers such as polythiourethane and TiO2 hybrid high refractive index films which not only retain their original properties but also have higher refractive indices.Moreover, Hybrid systems of nanoparticles and different polymers such as poly (N, N-dimethylacrylamide) / ZnS hybrid materials, polyurethane / PbS hybrid materials, etc. Organic-inorganic hybrid materials can not only prepare high refractive index Rate materials can also be used to prepare high-performance photoluminescence bulk materials. Surface negatively charged CdTe nanocrystals can be transferred from the aqueous phase to the oil phase by electrostatic interaction, and finally by the free radical polymerization, to obtain uniform distribution of nanocrystals Of the bulk material, and polymer molecules in turn can also be used as an excellent medium for controlling the growth of nanocrystals to achieve precise control of nanocrystal size and performance optimization of the luminescent color under UV light The size of the nanocrystals into the controlled size of the functional polymer poly-p-phenylene vinylene (PPV) precursor with CdTe nanocrystals can be used to prepare pure white light-emitting hybrid materials, as well as high-performance Solar cell devices.
