摘要: Disclosed is a quantum dot composition comprising: a polycarbonate resin, a polycarbonate copolymer resin, or a combination thereof; a quantum dot concentrate including a plurality of nanoparticle quantum dots and an acrylic polymer, a methacrylic polymer, or a combination thereof; and a compatibilizer for promoting dispersion of the nanoparticle quantum dots in the quantum dot composition. The compatibilizer includes a transesterification catalyst, a physical compatibilizer, a plurality of semiconductor nanopartides passivated with a metal oxide, or a combination thereof. Further disclosed is a method for making a quantum dot composition, the method including: forming a quantum dot concentrate by combining a plurality of nanoparticle quantum dots with an acrylic polymer, a methacrylic polymer or a combination thereof; and combining the quantum dot concentrate with a compatibilizer and a polycarbonate resin, a polycarbonate copolymer resin, or a combination thereof.

摘要: A polyimide composition includes 1 to 99 weight percent, preferably 70 to 99 weight percent, more preferably 75 to 95 weight percent of a first polyimide; and 1 to 99 weight percent, preferably 1 to 30 weight percent, more preferably 2 to 25 weight percent of a second polyimide, wherein the first polyimide and the second polyimide are different, and wherein the polyimide composition has a melt flow rate that is greater than a melt flow rate of the first polyimide and less than a melt flow rate of the second polyimide; an apparent viscosity that is less than an apparent viscosity of the first polyimide and less than an apparent viscosity of the second polyimide; and a notched Izod impact strength that is greater than a notched Izod impact strength of the first polyimide and greater than a notched Izod impact strength of the second polyimide.
