透過率を制御する方法に関するものである。DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a method for controlling the fluid permeability of a fluid permeable membrane that permeates gas or liquid.

うにして流体透過膜の流体透過率が制御される。Conventionally, as a method for controlling the fluid permeability of this type of fluid permeable membrane, there is a method of adjusting the temperature of the fluid permeable membrane. That is, if the temperature of the fluid-permeable membrane is increased, the thermal motion of the fluid-permeable membrane increases accordingly, and therefore the intermolecular distance increases. Thus, as the intermolecular distance increases, the diameter of the micropores of the fluid-permeable membrane increases accordingly. In this way, the fluid permeability of the fluid permeable membrane is controlled.

る。When an oscillating magnetic field is applied to a fluid-permeable membrane, the molecules constituting the fluid-permeable membrane are excited by the oscillating magnetic field, thereby increasing their molecular motion. Due to the increase in molecular motion, the distance between molecules increases, and therefore the diameter of the microbore of the fluid permeable membrane also increases. The molecular motion, ie, the diameter of the micropores, can be controlled by the frequency and intensity of the oscillating magnetic field.
