The method of manufacturing a polymer laminated substrate for forming an epitaxial growth film includes the steps of: activating at least one surface of a polymer sheet T1; activating at least one surface of a metal foil T2 which is made of Cu or a Cu alloy and is formed by cold rolling at a draft of 90% or more; laminating the polymer sheet and the metal foil such that an activated surface of the polymer sheet and an activated surface of the metal foil face each other in an opposed manner and applying cold rolling to the polymer sheet and the metal foil which are laminated to each other; and biaxially orienting crystals of the metal foil by heat treatment.
摘要:
A method of manufacturing a hydrogen separation membrane with a carrier is characterized by including a first step of providing, between the hydrogen separation membrane and the carrier that supports the hydrogen separation membrane, a low-hardness metal membrane having a hardness that is lower than the hardness of the hydrogen separation membrane, and a second step of joining the hydrogen separation membrane, the low-hardness metal membrane, and the carrier by a cold joining method. In this case, it is possible to suppress the deformation of the hydrogen separation membrane, the low-hardness metal membrane, and the carrier and, as a result, it is possible to prevent damaging of the hydrogen separation membrane. The adhesion of the contact between the hydrogen separation membrane and the carrier is also improved. The result is that it is not necessary to increase the severity of the cold joining conditions.
