Continuous production process for polytetrafluoroethylene functional film for electro-mechanical energy conversion |
摘要 |
A continuous production process for a polytetrafluoroethylene functional film for electro-mechanical energy conversion is disclosed. The process includes a step of thermal bonding a composite film having a micro-porous structure and electrically charging the composite film. The composite film having a micro-porous structure includes one layer of porous polytetrafluoroethylene film sandwiched between two adjacent layers of polytetrafluoroethylene film thermally bonded by two heated rollers. The process also has a step of electrically charging the composite film to obtain a polytetrafluoroethylene piezoelectric electret film. The electrically charging the composite film can be corona-polarizing the composite film by introducing the composite film between an electrode roller and a corona electrode, or introducing the composite film into an electroplating region and attaching electrodes to the upper and lower surfaces thereof, followed by introducing the film to a charging region by a contacting process. |
