Title:
LAMINATE AND METHOD FOR MANUFACTURING THE SAME
Document Type and Number:
Japanese Patent JP2021140867
Kind Code:
A
Abstract:
To provide a laminate including a polyelectrolyte membrane and a base material, in which a polyelectrolyte membrane with high hydrophilicity and a base material that is often hydrophobic are strongly bonded to each other.SOLUTION: There is provided a laminate which includes a polyelectrolyte membrane and a base material laminated via an adhesive layer therein. The adhesive layer is composed of polydopamine, and the base material has an acid functional group on the surface thereof. There is also provided a method for manufacturing the laminate, which includes the following steps 1-3. Step 1: a step of introducing an acid functional group on a base material surface. Step 2: a step of forming a polydopamine layer on the base material surface. Step 3: a step of applying a polyelectrolyte solution on at least one of the base material surface or a polyelectrolyte membrane surface, and then laminating both a base material and a polyelectrolyte membrane.SELECTED DRAWING: None
