Definitions
- the present invention relates to a molded body, a manufacturing method thereof, an electronic device member made of the molded body, and an electronic device including the electronic device member.
- Patent Documents 1 and 2 propose gas barrier sheets in which a smooth layer is provided on a synthetic resin sheet and a gas barrier inorganic compound thin film is further laminated.
- the gas barrier sheets described in these documents have poor interlayer adhesion between the smooth layer and the inorganic material layer that serves as the gas barrier layer or electrode material, and a functional thin film for improving interlayer adhesion is provided for each interlayer. It was necessary to provide a thick film of the resulting gas barrier sheet, and the number of steps involved therewith was a problem.
- Patent Document 3 discloses a method for producing a gas barrier film by forming a polysilazane film on at least one surface of a film and subjecting the polysilazane film to plasma treatment.
- this method has a problem in that sufficient gas barrier performance cannot be obtained unless the thickness of the gas barrier layer is in the micron order. For example, when the thickness of the gas barrier layer is 0.1 ⁇ m, it is described that the water vapor transmission rate is 0.50 g / m 2 / day.
- the present invention has been made in view of the above-described prior art, and includes a molded body excellent in interlayer adhesion and gas barrier properties, a manufacturing method thereof, an electronic device member formed of the molded body, and the electronic device member. It is an object to provide an electronic device.
- the present inventors have obtained a molded body in which a base material layer, a primer layer and a gas barrier layer are laminated in this order, and the primer layer has at least carbon atoms, oxygen It is composed of a material containing an atom and a silicon atom, and having a peak position of the binding energy of the 2p electron orbit of the silicon atom of 101.5 to 104 eV in the X-ray photoelectron spectroscopy (XPS) measurement
- the gas barrier layer is a layer obtained by implanting ions into a polymer layer containing at least one selected from the group consisting of a polysilazane compound, a polyorganosiloxane compound, a polysilane compound, and a polycarbosilane compound, Alternatively, it is composed of a material containing at least oxygen atoms and silicon atoms, and in the surface layer portion, the presence ratio of oxygen atoms is 60 to 75% with respect to the total amount
- Such a molded body contains at least a carbon atom, an oxygen atom, and a silicon atom, and in X-ray photoelectron spectroscopy (XPS) measurement, the peak position of the binding energy of the 2p electron orbit of the silicon atom is 101.5 to On the surface of the base material having a primer layer composed of a material of 104 eV formed on the surface, selected from the group consisting of a polysilazane compound, a polyorganosiloxane compound, a polycarbosilane compound and a polysilane compound After forming a polymer layer containing at least one kind of the polymer, it was found that it can be easily and efficiently produced by implanting ions into the surface portion of the polymer layer, and the present invention has been completed.
