Abstract
A transparent and heat-resistant polycarbonate (PC) composite and a preparation method thereof. The PC composite is a blend of a PC, a polyarylester (PAR) and an organic salt. The preparation method includes: drying the PC and the PAR each under vacuum at 80-120° C. for 24-48 h; adding the dried PC, the dried PAR and the organic salt into a melt blending device at a mass ratio of (60-90):(40-10):(0.3-3), and performing melt blending at 250-300° C. to obtain a mixture; and discharging the mixture from the melt blending device, and cooling to normal temperature to obtain a PC composite.
