제목 Siloxane bound polyimides and convenient coating of dielectric film on Al-plate heater
초록 The polyimide has been widely employed in electric heating field because of excellent dielectric strength and heat transfer efficiency, and resistance stability in high temperature. Polyimide Film based plate heater (~100um thickness) was composed of two external insulator layers and metal foil layer for the electrical heat generation. Adhesive property of polyimides on metal surface become weaken with increasing temperature from the different thermal expansions of metal and organic polymers. The fabrication of conventional laminate heater was supplemented by an interlayer functioning as a glue. This research was to develop new thermal polyimides with siloxane chains covalently bound onto a polyimide backbone for the enhanced adhesiveness. The polymer film was optimized with the amount of introducing siloxane through thermal gravimetric analysis. Additional polyimide analogues from thermally cured polymerization was suggested for a convenient and fast fabrication process.
