Abstract
Official abstract text for this publication.
A molded article containing a crystal of a fluoropolymer. The fluoropolymer contains at least one selected from vinylidene fluoride/tetrafluoroethylene copolymer, polychlorotrifluoroethylene, an ethylene/tetrafluoroethylene copolymer, a tetrafluoroethylene/perfluoro(alkyl vinyl ether) copolymer and a tetrafluoroethylene/hexafluoropropylene copolymer. Further, the crystal is a nano-oriented crystal having a size of 300 nm or smaller.
First claim
Opening claim text (preview).
The invention claimed is: 1. A molded article comprising a crystal of a fluoropolymer, the fluoropolymer comprising at least one selected from the group consisting of a polychlorotrifluoroethylene containing CTFE unit in an amount of from 90 to 100 mol % relative to the fluoropolymer, an ethylene/tetrafluoroethylene copolymer which may contain units copolymerizable with TFE and ethylene in an amount of up to 10 mol % relative to the fluoropolymer, a tetrafluoroethylene/perfluoro(alkyl vinyl ether) copolymer which may contain units copolymerizable with TFE and PAVE unit in an amount of up to 10 mol % relative to the fluoropolymer, and a tetrafluoroethylene/hexafluoropropylene copolymer which may contain units copolymerizable with the TFE unit and HFP unit in an amount of up to 10 mol % relative to the fluoropolymer, the crystal being a nano-oriented crystal having a size of 300 nm or smaller. 2. A speaker, a piezoelectric sensor, a high-speed switching device, a vibration-powered generator, a imaging device, a wearable sensor, an electrowetting device, a capacitor, a building material sheet, a roof materials of a building, a chemical liquid container, a rubber closure, or a fixing and pressure roller, comprising the molded article according to claim 1 .
