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 %.

Abstract: Thermoplastic compositions include: at least one polyamide resin; at least about 30 wt % of a reinforcing fiber; and an impact modifier component including at least one impact modifier having a glass transition temperature (Tg) of about −30 degrees Celsius (° C.) or lower. The reinforcing fiber has a fiber length of at least about 10 millimeters (mm). The thermoplastic composition has a notched Izod impact strength of at least 300 Joules per meter (J/m) at −40° C. and a multi-axial impact energy of at least 15 J at −40° C. Methods of forming a pelletized thermoplastic composition, a plurality of thermoplastic pellets, and a composition including the plurality of thermoplastic pellets are also described.
