Abstract

Disclosed is a formed article comprising a layer obtained by implanting ions of a hydrocarbon compound into a polyorganosiloxane compound-containing layer. Also disclosed are: a method of producing the formed article, the method comprising implanting ions of a hydrocarbon compound into a surface of a polyorganosiloxane compound-containing layer of a formed body that includes the polyorganosiloxane compound-containing layer in its surface; an electronic device member that includes the formed article; and an electronic device that includes the electronic device member. The present invention provides; a formed article which exhibits an excellent gas barrier capability, transparency, bendability, antistatic performance, and surface flatness; a method of producing the formed article, an electronic device member, and an electronic device.

First claim

The invention claimed is:

1. A method of producing a formed article having a base and a layer formed on the base and obtained by implanting ions of a hydrocarbon compound into a polyorganosiloxane compound-containing layer, the base being formed of a material selected from the group consisting of polyimides, polyamides, polyamideimides, polyphenylene ethers, polyether ketones, polyether ether ketones, polyolefins, polyesters, polycarbonates, polysulfones, polyether sulfones, polyphenylene sulfides, polyallylates, acrylic resins, cycloolefin polymers, and aromatic polymers,
the method comprising implanting ions of a hydrocarbon compound into a surface of a polyorganosiloxane compound-containing layer of a formed body that includes the polyorganosiloxane compound-containing layer in its surface, wherein the hydrocarbon compound is selected from the group consisting of an alkene gas, an alkadiene gas, an alkyne gas, a cycloalkane gas and a cycloalkane gas,
wherein the formed article has a low water vapor transmission rate of 0.15 to 2.80 g/m2/day,
wherein the main chain structure of the polyorganosiloxane compound is a straight chain structure shown by the following formula (a), a ladder-like structure shown by the following formula (b), or a polyhedral structure shown by the following formula (c),

wherein Rx, Ry, and Rz individually represent a hydrogen atom, a non-hydrolysable group selected from the group consisting of a substituted alkyl group whose substituent is halogen atoms, a hydroxyl group, a thiol group, an epoxy group, a glycidoxy group, an unsubstituted phenyl groups, a substituted alkenyl group whose substituent is halogen atoms, a hydroxyl group, a thiol group, an epoxy group, a glycidoxy group, or an unsubstituted phenyl groups; an unsubstituted alkenyl group; a substituted aryl group whose substituent is halogen atoms, alkyl groups having 1 to 6 carbon atoms, alkoxy groups having 1 to 6 carbon atoms, a nitro group, a cyano group, a hydroxyl group, a thiol group, an epoxy group and a glycidoxy group, provided that a case where both Rx in the formula (a) represent a hydrogen atom is excluded.

2. The method according to claim 1 , comprising implanting ions of the hydrocarbon compound into a polyorganosiloxane compound-containing layer while carrying a formed body that includes the polyorganosiloxane compound-containing layer in its surface in a given direction, wherein the hydrocarbon compound is selected from the group consisting of an alkene gas, an alkadiene gas, an alkyne gas, a cycloalkane gas and a cycloalkane gas.

3. The method according to claim 1 , wherein the content of the polyorganosiloxane compounds in the polyorganosiloxane compound-containing layer is 70 wt % or more.

4. The method according to claim 1 , wherein the formed article produced has a water vapor transmission rate of 1.5 g/m 2 /day or less at a temperature of 40° C. and a relative humidity of 90%.

5. The method according to claim 1 , wherein the formed article produced has a surface resistivity of 1.1×10 14 Ω/square or less.
