Abstract: A nano-composite includes a thermoplastic copolymer includes a polycarbonate copolymer including repeating siloxane units and a plurality of quantum dots. A method of making a polymer film includes forming a masterbatch composition by combining (1) a first thermoplastic copolymer including a polycarbonate copolymer including repeating siloxane units and (2) a plurality of quantum dots; combining the masterbatch composition with a second thermoplastic polymer to form a mixture; and forming the polymer film from the mixture. The polycarbonate copolymer has a siloxane content of from 15 wt % to 65 wt %.
