A novel polycarbonate composite for waveguides.

ABSTRACT: The novel polycarbonate resin compositions comprising polycarbonate (PC) and acrylic resin were prepared by solution blending and analyzed by differential scanning calorimetry, atomic force microscopy, gel permeation chromatography, and gas chromatography‐mass spectrometry. Furthermore, the optical performance and the thermal and mechanical properties were tested, respectively. The results demonstrate that the blended material which was prepared by 100 parts of PC and 0.05 parts of acrylic resin achieves excellent transparency in blue‐light region (280–400 nm). Meanwhile, it retains excellent high‐heat resistance and mechanical performance of PC. Because of its high transparency in the blue‐light region which is caused by a doping of a tiny amount of acrylic resin, this material takes steps towards solving the optical problem that light becomes yellow when leaving the end of waveguides of PC. © 2018 Wiley Periodicals, Inc.
