| 摘要 |
A method of manufacturing new materials for a printed circuit board and Low-Earth Orbit (LEO) spacecraft is provided. The present invention includes dinitro, diamine, various phosphorous-containing polyimides and polyamides, and synthesizing methods thereof. The polymers of the embodiment of present invention exhibit good flame retardancy, high glass transition temperature, good mechanical properties and superior oxygen resistance, so they are good materials for Low-Earth Orbit applications. Besides, these polymers can also be used as matrix for halogen-free flexible printed circuit board.
