Abstract

The invention discloses a high-temperature-resistant organic flexible electrothermal film and a preparation method thereof. The high-temperature-resistant organic flexible electrothermal film is composed of a composite electricity conducting film and a composite heat conducting film. The composite heat conducting film is prepared from polyethylene terephthalate, dimethyl silicone oil, heat conducting filler, antioxygen and an anti-ultraviolet agent. The composite electricity conducting film is prepared from polyaniline, polyacetylene, carbon fibers, electricity conducting particles, fire retardant and lubricant. The organic flexible electrothermal film has excellent heat and electricity conducting performance and superhigh energy conversion efficiency, the energy utilization rate is increased, good mechanical performance is achieved, electrical performance is not affected after the organic flexible electrothermal film is repeatedly folded 20,000 times, and therefore the organic flexible electrothermal film can meet the heating use requirements of multiple irregular parts; the organic flexible electrothermal film further has excellent corrosion resistance, can be used under high-temperature and corrosive conditions for a long time, and is easy to prepare and suitable for industrial production.

Description

technical field [0001] The invention relates to the technical field of an organic electrothermal film and a preparation method thereof, in particular to a high-temperature-resistant organic flexible electrothermal film and a preparation method thereof. Background technique [0002] Electric heating film is a high-efficiency energy-saving product. On the World Environment Day in June 2004, a special program broadcast by CCTV mentioned: The current energy situation in the world, according to the current world industrialization development speed and energy consumption, the world's oil reserves are sufficient 40 years, natural gas reserves are sufficient for 60 years, and coal reserves are sufficient for 200 years. Energy conservation and the development of renewable energy are top priorities for all mankind. As an emerging technology, electrothermal film technology will surely produce good economic and social benefits when widely used. my country is an energy-short country, an...
