The present invention relates to a composite sheet including a polymer nanocomposite layer and a method for producing the same. The method of the present invention includes the steps of: preparing a clay solution and a graphene oxide solution; generating a mixture by mixing the clay solution and the graphene oxide solution with a polymer binder; producing a coating liquid by adding a fluorine-based additive and an antifoamer to the mixture; and forming a polymer nanocomposite layer by application of the coating liquid onto a substrate. The composite sheet including a polymer nanocomposite layer which is produced according to an aspect of the present invention has excellent heat conduction characteristics and is capable of efficiently discharging to the outside heat generated in electronic equipment. Accordingly, the lifespan of the electronic equipment can be extended and efficiency of the electronic equipment can be improved. In addition, the composite sheet including a polymer nanocomposite layer which is produced according to an aspect of the present invention is capable of preventing moisture penetration from the outside by containing clay, and thus is capable of extending the lifespan of the electronic equipment. Furthermore, the composite sheet according to the present invention is subjected to no significant decline in optical properties, such as optical transmittance and haze, while containing both graphene oxide and the clay, and thus can be applied in various ways to a field requiring transparency. |
