Title:
METHOD FOR PRODUCING SURFACE-MODIFIED TETRAFLUOROETHYLENE-BASED POLYMER, METHOD FOR PRODUCING MODIFIED POWDER, LIQUID COMPOSITION, METHOD FOR PRODUCING MODIFIED MOLDED ARTICLE, AND MODIFIED MOLDED ARTICLE
Document Type and Number:
WIPO Patent Application WO/2021/187456
Kind Code:
A1
Abstract:
[Problem] To provide: a method for producing a modified tetrafluoroethylene-based polymer and a powder by modifying a tetrafluoroethylene-based polymer and a powder of the polymer; and a method for producing a modified molded article by highly modifying the surface of a molded article of a tetrafluoroethylene-based polymer. [Solution] A method for producing a modified tetrafluoroethylene-based polymer and a powder, the method comprising subjecting a tetrafluoroethylene-based polymer and a powder of the polymer to a plasma treatment under an atmosphere having a pressure close to the atmospheric pressure to produce a surface-modified tetrafluoroethylene-based polymer; and a method for producing a molded article which has, as at least a portion of the surface thereof, a modified layer formed by introducing a hydrogen atom into a tetrafluoroethylene-based polymer, the method comprising subjecting a surface layer of a molded article having, as at least a portion of the surface layer thereof, a surface layer comprising the tetrafluoroethylene-based polymer to a plasma treatment under an atmosphere containing a reducing gas having a hydrogen atom and having a pressure close to the atmospheric pressure.
