Latest Patents

Karthikeyan holds a patent for "Colorless transparent copolyamide-imide films with high modulus and low coefficient of thermal expansion and preparation thereof." This patent discloses a method for preparing a colorless transparent copolyamide-imide resin solution and its fabrication as a thin film. The method involves formulations derived from a reaction between one or more units of dianhydride and one or more units of diamine monomers, with some monomers containing fluorine atoms. This innovative approach enables the creation of thin films with superior thermal and mechanical properties, achieving coefficient of thermal expansion values as low as 2 ppm/°C and a tensile modulus as high as 9 GPa. The resulting transparent copolyamide-imide film is poised for use in flexible displays, including substrates for thin film transistors (TFT), touch sensor panels (TSP), and cover windows in organic light-emitting diode (OLED) and liquid crystal display (LCD) applications.
