Abstract

Official abstract text for this publication.

A filter molded article using a graphene with water passage holes having a desired size is produced in a simple step. A method for producing a filter molded article having a graphene layer as a filtering material is characterized by including a step of forming a support 3 layer on a surface of a graphene 1 layer formed on initial substrates for a graphene 2 and 9, a step of forming water passage holes in the support 3 layer, a step of removing the initial substrates for a graphene 2 and 9, and a step of forming water passage holes by heating and holding the graphene 1 layer at a low temperature in the air containing oxygen of 160 to 250 ° C. for a predetermined time.

First claim

Opening claim text (preview).

1 . A method for producing a filter molded article having a graphene layer as a filter material, the method comprising: forming a support layer on a surface of the graphene layer formed on an initial substrate for a graphene; forming water passage holes in the support layer; removing the initial substrate for the graphene; and forming water passage holes by heating and holding the graphene layer at a low temperature in the air containing oxygen of 160 to 250° C. for a predetermined time. 2 . The method for producing the filter molded article according to claim 1 , wherein: the support is a negative photoresist, and the step of forming water passage holes in the support layer comprises exposing portions other than portions in which water passage holes of the photoresist should be formed to light. 3 . The method for producing the filter molded article according to claim 1 , wherein the step of forming water passage holes by heating and holding the graphene layer at a low temperature is performed in the air containing oxygen of 200 to 250° C.
