Abstract
The present invention relates to a porous sheet and a method for manufacturing the porous sheet. A porous sheet including a fine-fiber web layer and a support layer and a method for manufacturing the same are provided, and it is possible to implement a porous sheet with sufficient strength and thickness to be used in peeling and laminating processes of a multilayer ceramic capacitor.
Claims2
A method for manufacturing a porous sheet comprising:
- a spinning solution preparing step of preparing a spinning solution by mixing a polymer solution in which a polymer is dissolved and an adhesive solution in which an adhesive material is dissolved;
- an electrospinning step of forming fine-fibers in which the polymer and the adhesive material are mixed by electrospinning the spinning solution;
- an adhesive solution spraying step of spraying the adhesive solution in which the adhesive material is dissolved toward the fine-fibers;
- and
- a fine-fiber web layer forming step of forming a fine-fiber web layer by coupling the fine-fibers passed through the adhesive solution spraying step to a support layer.
