MODIFIED POLYSILAZANE FILM AND METHOD FOR PRODUCING GAS BARRIER FILM

摘要

Provided are: a modified polysilazane film which is suitable as an intermediate material for forming a specific gas barrier film; and a method for producing a gas barrier film having excellent gas barrier characteristics, said gas barrier film using the modified polysilazane film as an intermediate material. A modified polysilazane film which is obtained by forming a modified polysilazane layer on a base; and a method for producing a gas barrier film using such an intermediate material, wherein the thickness of the modified polysilazane layer is set to a value within the range of 10-500 nm and the refractive index of the modified polysilazane layer is set to a value within the range of 1.48-1.63.
