First Claim
Patent Images
1. A method for preparing a moisture barrier composite film, comprising:
- providing a graphene dispersed solution;
dissolving cyclic olefin copolymer in the graphene dispersed solution to obtain a casting solution;
performing a solution film casting procedure to coat the casting solution on a glass substrate to form a coating film; and
performing a film drying procedure to dry the coating film to separate from the glass substrate to obtain a moisture barrier composite film.

Abstract
The invention provides a moisture barrier composite film, formed by having a mixture of thermally reduced graphene and cyclic olefin copolymer be formed into a film and forming a hydrophilic surface layer on surfaces of the moisture barrier composite film by a hydrophilic agent; wherein a ratio of carbon atoms to oxygen atoms in thermally reduced graphene is more than 30 and the hydrophilic surface layer has a density of 0.01˜1.0 mg/cm2.
