Polymer-nanocrystals composite materials have attracted much attention for combining the advantage of both the organic and inorganic materials

the polymer provides an inert environment for the formation and growth of the nanocrystals

and nanocrystals in return enhance the performance of the polymer.Such as the TiO2-triethoxysilanecapped polythiourethane (TCPTU) composite optical films

the films not only retained the origin properties but also achieved a high refractive index.Besides

there are lots of different polymer-nanocrystals composite materials such as PDMAA/ZnS

PbS/PTU nanocomposites.The organic-inorganic materials could also be used to prepare the high performance photoluminescence materials besides the high refractive optical films.CdTe nanocrystals covered with negative charge could be transferred from water to organic solvent through the electrostatic force.At last

through radical polymerization

the bulk materials with a uniform distribution of the nanocrystals could be obtained.In turn

polymer could be used as a friend media to control the growth of the CdTe nanocrystals and realize the precise control and the performance optimization.The luminescent color under the UV light could be controlled by changing the size of the nanocrystals.What's more

as a kind of functional polymer

PPV precursor could be combined with CdTe nanocrystals to prepare pure white-light composite materials and also high performance photovoltaic devices.
